 <p>The <span class="math inline">\(\chi^2\)</span> error level of 14% suggests that the model does not fit very well. This is also obvious from the plots of the fit, in which we have included the residual plot.</p>
 <p>In the FOCUS kinetics report, it is stated that there is no apparent systematic error observed from the residual plot up to the measured DT90 (approximately at day 5), and there is an underestimation beyond that point.</p>
 <p>We may add that it is difficult to judge the random nature of the residuals just from the three samplings at days 0, 1 and 3. Also, it is not clear <em>a priori</em> why a consistent underestimation after the approximate DT90 should be irrelevant. However, this can be rationalised by the fact that the FOCUS fate models generally only implement SFO kinetics.</p>

 <p>As of mkin version 0.9-39 (June 2015), we can fit several models to one or more datasets in one call to the function <code>mmkin</code>. The datasets have to be passed in a list, in this case a named list holding only the L3 dataset prepared above.</p>

 <p>The <span class="math inline">\(\chi^2\)</span> error level of 21% as well as the plot suggest that the SFO model does not fit very well. The FOMC model performs better, with an error level at which the <span class="math inline">\(\chi^2\)</span> test passes of 7%.

 <p>Here, a look to the model plot, the confidence intervals of the parameters and the correlation matrix suggest that the parameter estimates are reliable, and the DFOP model can be used as the best-fit model based on the <span class="math inline">\(\chi^2\)</span> error level criterion for laboratory data L3.</p>
 <p>This is also an example where the standard t-test for the parameter <code>g_ilr</code> is misleading, as it tests for a significant difference from zero. In this case, zero appears to be the correct value for this parameter, and the confidence interval for the backtransformed parameter <code>g</code> is quite narrow.</p>

+\section{Parent compound and one metabolite}
+
+The next step is to set up the models used for the kinetic analysis. As the 
+simultaneous fit of parent and the first metabolite is usually straightforward,
+Step 1 (SFO for parent only) is skipped here. We start with the model 2a, 
+with formation and decline of metabolite Z1 and the pathway from parent
+directly to sink included (default in mkin).
+
+<<FOCUS_2006_Z_fits_1, echo=TRUE, fig.height=6>>=
+Z.2a <- mkinmod(Z0 = mkinsub("SFO", "Z1"),
+                Z1 = mkinsub("SFO"))
+m.Z.2a <- mkinfit(Z.2a, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.2a)
+summary(m.Z.2a, data = FALSE)$bpar
+@
+
+As obvious from the parameter summary (the \texttt{bpar} component of the 
+summary), the kinetic rate constant from parent compound Z to sink
+is negligible. Accordingly, the exact magnitude of the fitted parameter 
+\texttt{log k\_Z0\_sink} is ill-defined and the covariance matrix is not
+returned (not shown, would be visible in the complete summary). 
+This suggests, in agreement with the analysis in the FOCUS kinetics report, to
+simplify the model by removing the pathway to sink.
+
+A similar result can be obtained when formation fractions are used in the model 
+formulation:
+
+<<FOCUS_2006_Z_fits_2, echo=TRUE, fig.height=6>>=
+Z.2a.ff <- mkinmod(Z0 = mkinsub("SFO", "Z1"),
+                   Z1 = mkinsub("SFO"),
+                   use_of_ff = "max")
+
+m.Z.2a.ff <- mkinfit(Z.2a.ff, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.2a.ff)
+summary(m.Z.2a.ff, data = FALSE)$bpar
+@
+
+Here, the ilr transformed formation fraction fitted in the model takes a very
+large value, and the backtransformed formation fraction from parent Z to Z1 is
+practically unity. Again, the covariance matrix is not returned as the model is
+overparameterised. 
+
+The simplified model is obtained by setting the list component \texttt{sink} to
+\texttt{FALSE}.\footnote{If the model formulation without formation fractions
+is used, the same effect can be obtained by fixing the parameter \texttt{k\_Z\_sink}
+to a value of zero.} 
+
+In the following, we use the parameterisation with formation fractions in order
+to be able to compare with the results in the FOCUS guidance, and as it 
+makes it easier to use parameters obtained in a previous fit when adding a further 
+metabolite.
+
+<<FOCUS_2006_Z_fits_3, echo=TRUE, fig.height=6>>=
+Z.3 <- mkinmod(Z0 = mkinsub("SFO", "Z1", sink = FALSE),
+               Z1 = mkinsub("SFO"), use_of_ff = "max")
+m.Z.3 <- mkinfit(Z.3, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.3)
+summary(m.Z.3, data = FALSE)$bpar
+@
+
+As there is only one transformation product for Z0 and no pathway
+to sink, the formation fraction is internally fixed to unity.
+
+\section{Including metabolites Z2 and Z3}
+
+As suggested in the FOCUS report, the pathway to sink was removed for metabolite Z1 as
+well in the next step. While this step appears questionable on the basis of the above results, it 
+is followed here for the purpose of comparison. Also, in the FOCUS report, it is 
+assumed that there is additional empirical evidence that Z1 quickly and exclusively
+hydrolyses to Z2. 
+
+<<FOCUS_2006_Z_fits_5, echo=TRUE, fig.height=7>>=
+Z.5 <- mkinmod(Z0 = mkinsub("SFO", "Z1", sink = FALSE),
+               Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+               Z2 = mkinsub("SFO"), use_of_ff = "max")
+m.Z.5 <- mkinfit(Z.5, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.5)
+@
+
+Finally, metabolite Z3 is added to the model. We use the optimised
+differential equation parameter values from the previous fit in order to
+accelerate the optimization.
+
+<<FOCUS_2006_Z_fits_6, echo=TRUE, fig.height=8>>=
+Z.FOCUS <- mkinmod(Z0 = mkinsub("SFO", "Z1", sink = FALSE),
+                   Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+                   Z2 = mkinsub("SFO", "Z3"),
+                   Z3 = mkinsub("SFO"), 
+                   use_of_ff = "max")
+m.Z.FOCUS <- mkinfit(Z.FOCUS, FOCUS_2006_Z_mkin, 
+                     parms.ini = m.Z.5$bparms.ode,
+                     quiet = TRUE)
+plot_sep(m.Z.FOCUS)
+summary(m.Z.FOCUS, data = FALSE)$bpar
+endpoints(m.Z.FOCUS)
+@
+
+This fit corresponds to the final result chosen in Appendix 7 of the FOCUS
+report. Confidence intervals returned by mkin are based on internally
+transformed parameters, however.
+
+\section{Using the SFORB model for parent and metabolites}
+
+As the FOCUS report states, there is a certain tailing of the time course of metabolite 
+Z3. Also, the time course of the parent compound is not fitted very well using the 
+SFO model, as residues at a certain low level remain.
+
+Therefore, an additional model is offered here, using the single first-order 
+reversible binding (SFORB) model for metabolite Z3. As expected, the $\chi^2$
+error level is lower for metabolite Z3 using this model and the graphical 
+fit for Z3 is improved. However, the covariance matrix is not returned.
+
+<<FOCUS_2006_Z_fits_7, echo=TRUE, fig.height=8>>=
+Z.mkin.1 <- mkinmod(Z0 = mkinsub("SFO", "Z1", sink = FALSE),
+                    Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+                    Z2 = mkinsub("SFO", "Z3"),
+                    Z3 = mkinsub("SFORB"))
+m.Z.mkin.1 <- mkinfit(Z.mkin.1, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.mkin.1)
+summary(m.Z.mkin.1, data = FALSE)$cov.unscaled
+@
+
+Therefore, a further stepwise model building is performed starting from the
+stage of parent and two metabolites, starting from the assumption that the model
+fit for the parent compound can be improved by using the SFORB model.
+
+<<FOCUS_2006_Z_fits_9, echo=TRUE, fig.height=8>>=
+Z.mkin.3 <- mkinmod(Z0 = mkinsub("SFORB", "Z1", sink = FALSE),
+                    Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+                    Z2 = mkinsub("SFO"))
+m.Z.mkin.3 <- mkinfit(Z.mkin.3, FOCUS_2006_Z_mkin, quiet = TRUE)
+plot_sep(m.Z.mkin.3)
+@
+
+This results in a much better representation of the behaviour of the parent 
+compound Z0.
+
+Finally, Z3 is added as well. These models appear overparameterised (no
+covariance matrix returned) if the sink for Z1 is left in the models.
+
+<<FOCUS_2006_Z_fits_10, echo=TRUE, fig.height=8>>=
+Z.mkin.4 <- mkinmod(Z0 = mkinsub("SFORB", "Z1", sink = FALSE),
+                    Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+                    Z2 = mkinsub("SFO", "Z3"),
+                    Z3 = mkinsub("SFO"))
+m.Z.mkin.4 <- mkinfit(Z.mkin.4, FOCUS_2006_Z_mkin, 
+                      parms.ini = m.Z.mkin.3$bparms.ode,
+                      quiet = TRUE)
+plot_sep(m.Z.mkin.4)
+@
+
+The error level of the fit, but especially of metabolite Z3, can be improved if
+the SFORB model is chosen for this metabolite, as this model is capable of
+representing the tailing of the metabolite decline phase.
+
+<<FOCUS_2006_Z_fits_11, echo=TRUE, fig.height=8>>=
+Z.mkin.5 <- mkinmod(Z0 = mkinsub("SFORB", "Z1", sink = FALSE),
+                    Z1 = mkinsub("SFO", "Z2", sink = FALSE),
+                    Z2 = mkinsub("SFO", "Z3"),
+                    Z3 = mkinsub("SFORB"))
+m.Z.mkin.5 <- mkinfit(Z.mkin.5, FOCUS_2006_Z_mkin, 
+                      parms.ini = m.Z.mkin.4$bparms.ode[1:4],
+                      quiet = TRUE)
+plot_sep(m.Z.mkin.5)
+@
+
+The summary view of the backtransformed parameters shows that we get no
+confidence intervals due to overparameterisation. As the optimized
+\texttt{k\_Z3\_bound\_free} is excessively small, it seems reasonable to fix it to
+zero. 
+
+<<FOCUS_2006_Z_fits_11a, echo=TRUE>>=
+m.Z.mkin.5a <- mkinfit(Z.mkin.5, FOCUS_2006_Z_mkin, 
+                       parms.ini = c(m.Z.mkin.5$bparms.ode[1:7],
+                                     k_Z3_bound_free = 0),
+                       fixed_parms = "k_Z3_bound_free",
+                       quiet = TRUE)
+plot_sep(m.Z.mkin.5a)
+@
+
+As expected, the residual plots for Z0 and Z3 are more random than in the case of the 
+all SFO model for which they were shown above. In conclusion, the model
+\texttt{Z.mkin.5a} is proposed as the best-fit model for the dataset from
+Appendix 7 of the FOCUS report.
+
+A graphical representation of the confidence intervals can finally be obtained.
+
+<<FOCUS_2006_Z_fits_11b, echo=TRUE>>=
+mkinparplot(m.Z.mkin.5a)
+@
+
+The endpoints obtained with this model are
+
+<<FOCUS_2006_Z_fits_11b_endpoints, echo=TRUE>>=
+endpoints(m.Z.mkin.5a)
+@
+
+It is clear the degradation rate of Z3 towards the end of the experiment 
+is very low as DT50\_Z3\_b2 (the second Eigenvalue of the system of two differential 
+equations representing the SFORB system for Z3, corresponding to the slower rate
+constant of the DFOP model) is reported to be infinity.  However, this appears
+to be a feature of the data.

+\section{Parent compound and one metabolite}
+
+The next step is to set up the models used for the kinetic analysis. As the 
+simultaneous fit of parent and the first metabolite is usually straightforward,
+Step 1 (SFO for parent only) is skipped here. We start with the model 2a, 
+with formation and decline of metabolite Z1 and the pathway from parent
+directly to sink included (default in mkin).

+
+As obvious from the parameter summary (the \texttt{bpar} component of the 
+summary), the kinetic rate constant from parent compound Z to sink
+is negligible. Accordingly, the exact magnitude of the fitted parameter 
+\texttt{log k\_Z0\_sink} is ill-defined and the covariance matrix is not
+returned (not shown, would be visible in the complete summary). 
+This suggests, in agreement with the analysis in the FOCUS kinetics report, to
+simplify the model by removing the pathway to sink.
+
+A similar result can be obtained when formation fractions are used in the model 
+formulation:

+
+Here, the ilr transformed formation fraction fitted in the model takes a very
+large value, and the backtransformed formation fraction from parent Z to Z1 is
+practically unity. Again, the covariance matrix is not returned as the model is
+overparameterised. 
+
+The simplified model is obtained by setting the list component \texttt{sink} to
+\texttt{FALSE}.\footnote{If the model formulation without formation fractions
+is used, the same effect can be obtained by fixing the parameter \texttt{k\_Z\_sink}
+to a value of zero.} 
+
+In the following, we use the parameterisation with formation fractions in order
+to be able to compare with the results in the FOCUS guidance, and as it 
+makes it easier to use parameters obtained in a previous fit when adding a further 
+metabolite.

+
+As there is only one transformation product for Z0 and no pathway
+to sink, the formation fraction is internally fixed to unity.
+
+\section{Including metabolites Z2 and Z3}
+
+As suggested in the FOCUS report, the pathway to sink was removed for metabolite Z1 as
+well in the next step. While this step appears questionable on the basis of the above results, it 
+is followed here for the purpose of comparison. Also, in the FOCUS report, it is 
+assumed that there is additional empirical evidence that Z1 quickly and exclusively
+hydrolyses to Z2.

+
+This fit corresponds to the final result chosen in Appendix 7 of the FOCUS
+report. Confidence intervals returned by mkin are based on internally
+transformed parameters, however.
+
+\section{Using the SFORB model for parent and metabolites}
+
+As the FOCUS report states, there is a certain tailing of the time course of metabolite 
+Z3. Also, the time course of the parent compound is not fitted very well using the 
+SFO model, as residues at a certain low level remain.
+
+Therefore, an additional model is offered here, using the single first-order 
+reversible binding (SFORB) model for metabolite Z3. As expected, the $\chi^2$
+error level is lower for metabolite Z3 using this model and the graphical 
+fit for Z3 is improved. However, the covariance matrix is not returned.

+It is clear the degradation rate of Z3 towards the end of the experiment 
+is very low as DT50\_Z3\_b2 (the second Eigenvalue of the system of two differential 
+equations representing the SFORB system for Z3, corresponding to the slower rate
+constant of the DFOP model) is reported to be infinity.  However, this appears
+to be a feature of the data.

 <p>In the regulatory evaluation of chemical substances like plant protection products (pesticides), biocides and other chemicals, degradation data play an important role. For the evaluation of pesticide degradation experiments, detailed guidance has been developed, based on nonlinear optimisation. The <code>R</code> add-on package <code>mkin</code> <span class="citation">(Ranke 2016)</span> implements fitting some of the models recommended in this guidance from within R and calculates some statistical measures for data series within one or more compartments, for parent and metabolites.</p>

 <p>The now deprecated <code>kinfit</code> package <span class="citation">(Ranke 2015)</span> in <code>R</code> <span class="citation">(R Development Core Team 2016)</span> implements the approach recommended in the kinetics report provided by the FOrum for Co-ordination of pesticide fate models and their USe <span class="citation">(FOCUS Work Group on Degradation Kinetics 2006; 2014)</span> for simple data series for one parent compound in one compartment.</p>
 <p>The <code>mkin</code> package <span class="citation">(Ranke 2016)</span> extends this approach to data series with transformation products, commonly termed metabolites, and to more than one compartment. It is also possible to include back reactions, so equilibrium reactions and equilibrium partitioning can be specified, although this oftentimes leads to an overparameterisation of the model.</p>

 <p>Also, <code>mkin</code> introduced using analytical solutions for parent only kinetics for improved optimization speed. Later, Eigenvalue based solutions were introduced to <code>mkin</code> for the case of linear differential equations (<em>i.e.</em> where the FOMC or DFOP models were not used for the parent compound), greatly improving the optimization speed for these cases.</p>
 <p>The possibility to specify back-reactions and a biphasic model (SFORB) for metabolites were present in <code>mkin</code> from the very beginning.</p>

-<h2>Derived software tools</h2>
+<h2 class="hasAnchor"><html><body><a href="#derived-software-tools" class="anchor"> </a></body></html>Derived software tools</h2>
 <p>Soon after the publication of <code>mkin</code>, two derived tools were published, namely KinGUII (available from Bayer Crop Science) and CAKE (commissioned to Tessella by Syngenta), which added a graphical user interface (GUI), and added fitting by iteratively reweighted least squares (IRLS) and characterisation of likely parameter distributions by Markov Chain Monte Carlo (MCMC) sampling.</p>
 <p>CAKE focuses on a smooth use experience, sacrificing some flexibility in the model definition, originally allowing only two primary metabolites in parallel. The current version 3.2 of CAKE release in March 2016 uses a basic scheme for up to six metabolites in a flexible arrangement, but does not support back-reactions (non-instantaneous equilibria) or biphasic kinetics for metabolites.</p>
 <p>KinGUI offers an even more flexible widget for specifying complex kinetic models. Back-reactions (non-instanteneous equilibria) were supported early on, but until 2014, only simple first-order models could be specified for transformation products. Starting with KinGUII version 2.1, biphasic modelling of metabolites was also available in KinGUII.</p>
 <p>A further graphical user interface (GUI) that has recently been brought to a decent degree of maturity is the browser based GUI named <code>gmkin</code>. Please see its <a href="http://kinfit.r-forge.r-project.org/gmkin_static">documentation page</a> and <a href="http://kinfit.r-forge.r-project.org/gmkin_static/vignettes/gmkin_manual.html">manual</a> for further information.</p>

+<h2 class="hasAnchor"><html><body><a href="#recent-developments" class="anchor"> </a></body></html>Recent developments</h2>
 <p>Currently (June 2016), the main features available in <code>mkin</code> which are not present in KinGUII or CAKE, are the speed increase by using compiled code when a compiler is present, parallel model fitting on multicore machines using the <code>mmkin</code> function, and the estimation of parameter confidence intervals based on transformed parameters. These are explained in more detail below.</p>
 </div>
 </div>
 <div id="internal-parameter-transformations" class="section level1">
-<h1>Internal parameter transformations</h1>
+<h1 class="hasAnchor"><html><body><a href="#internal-parameter-transformations" class="anchor"> </a></body></html>Internal parameter transformations</h1>
 <p>For rate constants, the log transformation is used, as proposed by Bates and Watts <span class="citation">(1988, 77, 149)</span>. Approximate intervals are constructed for the transformed rate constants <span class="citation">(compare Bates and Watts 1988, 135)</span>, <em>i.e.</em> for their logarithms. Confidence intervals for the rate constants are then obtained using the appropriate backtransformation using the exponential function.</p>
 <p>In the first version of <code>mkin</code> allowing for specifying models using formation fractions, a home-made reparameterisation was used in order to ensure that the sum of formation fractions would not exceed unity.</p>
 <p>This method is still used in the current version of KinGUII (v2.1 from April 2014), with a modification that allows for fixing the pathway to sink to zero. CAKE uses penalties in the objective function in order to enforce this constraint.</p>
 <p>In 2012, an alternative reparameterisation of the formation fractions was proposed together with Ren&eacute; Lehmann <span class="citation">(Ranke and Lehmann 2012)</span>, based on isometric logratio transformation (ILR). The aim was to improve the validity of the linear approximation of the objective function during the parameter estimation procedure as well as in the subsequent calculation of parameter confidence intervals.</p>
 <div id="confidence-intervals-based-on-transformed-parameters" class="section level2">
-<h2>Confidence intervals based on transformed parameters</h2>
+<h2 class="hasAnchor"><html><body><a href="#confidence-intervals-based-on-transformed-parameters" class="anchor"> </a></body></html>Confidence intervals based on transformed parameters</h2>
 <p>In the first attempt at providing improved parameter confidence intervals introduced to <code>mkin</code> in 2013, confidence intervals obtained from FME on the transformed parameters were simply all backtransformed one by one to yield asymetric confidence intervals for the backtransformed parameters.</p>
 <p>However, while there is a 1:1 relation between the rate constants in the model and the transformed parameters fitted in the model, the parameters obtained by the isometric logratio transformation are calculated from the set of formation fractions that quantify the paths to each of the compounds formed from a specific parent compound, and no such 1:1 relation exists.</p>
 <p>Therefore, parameter confidence intervals for formation fractions obtained with this method only appear valid for the case of a single transformation product, where only one formation fraction is to be estimated, directly corresponding to one component of the ilr transformed parameter.</p>
 <p>The confidence intervals obtained by backtransformation for the cases where a 1:1 relation between transformed and original parameter exist are considered by the author of this vignette to be more accurate than those obtained using a re-estimation of the Hessian matrix after backtransformation, as implemented in the FME package.</p>
 </div>
 <div id="parameter-t-test-based-on-untransformed-parameters" class="section level2">
-<h2>Parameter t-test based on untransformed parameters</h2>
+<h2 class="hasAnchor"><html><body><a href="#parameter-t-test-based-on-untransformed-parameters" class="anchor"> </a></body></html>Parameter t-test based on untransformed parameters</h2>
 <p>The standard output of many nonlinear regression software packages includes the results from a test for significant difference from zero for all parameters. Such a test is also recommended to check the validity of rate constants in the FOCUS guidance <span class="citation">(FOCUS Work Group on Degradation Kinetics 2014, 96ff)</span>.</p>
 <p>It has been argued that the precondition for this test, <em>i.e.</em> normal distribution of the estimator for the parameters, is not fulfilled in the case of nonlinear regression <span class="citation">(Ranke and Lehmann 2015)</span>. However, this test is commonly used by industry, consultants and national authorities in order to decide on the reliability of parameter estimates, based on the FOCUS guidance mentioned above. Therefore, the results of this one-sided t-test are included in the summary output from <code>mkin</code>.</p>
 <p>As it is not reasonable to test for significant difference of the transformed parameters (<em>e.g.</em> <span class="math inline">\(log(k)\)</span>) from zero, the t-test is calculated based on the model definition before parameter transformation, <em>i.e.</em> in a similar way as in packages that do not apply such an internal parameter transformation. A note is included in the <code>mkin</code> output, pointing to the fact that the t-test is based on the unjustified assumption of normal distribution of the parameter estimators.</p>

 <p>It could not have been written without me being introduced to regulatory fate modelling of pesticides by Adrian Gurney during my time at Harlan Laboratories Ltd (formerly RCC Ltd). <code>mkin</code> greatly profits from and largely follows the work done by the <a href="http://focus.jrc.ec.europa.eu/dk">FOCUS Degradation Kinetics Workgroup</a>, as detailed in their guidance document from 2006, slightly updated in 2011 and in 2014.</p>

 <p>In 2011, Bayer Crop Science started to distribute an R based successor to KinGUI named KinGUII whose R code is based on <code>mkin</code>, but which added, amongst other refinements, a closed source graphical user interface (GUI), iteratively reweighted least squares (IRLS) optimisation of the variance for each of the observed variables, and Markov Chain Monte Carlo (MCMC) simulation functionality, similar to what is available e.g.&nbsp;in the <code>FME</code> package.</p>
 <p>Somewhat in parallel, Syngenta has sponsored the development of an <code>mkin</code> and KinGUII based GUI application called CAKE, which also adds IRLS and MCMC, is more limited in the model formulation, but puts more weight on usability. CAKE is available for download from the <a href="http://projects.tessella.com/cake">CAKE website</a>, where you can also find a zip archive of the R scripts derived from <code>mkin</code>, published under the GPL license.</p>
 <p>Finally, there is <a href="http://github.com/zhenglei-gao/KineticEval">KineticEval</a>, which contains a further development of the scripts used for KinGUII, so the different tools will hopefully be able to learn from each other in the future as well.</p>

Your <a href="https://help.github.com/articles/fork-a-repo">mkin fork</a> is just a mouse click away&hellip; The master branch on github should always be in good shape, I implement new features in separate branches now. If you prefer subversion, project members for the <a href="http://r-forge.r-project.org/R/?group_id=615">r-forge project</a> are welcome as well.
