@@ -2,6 +2,8 @@ ## NEW FEATURES +- The number of degrees of freedom is difficult to define in the case of ilr transformation of formation fractions. Now for each source compartment the number of ilr parameters (=number of optimised parameters) is divided by the number of pathways to metabolites (=number of affected data series) which leads to fractional degrees of freedom in some cases. + - The default for the initial value for the first state value is now taken from the mean of the observations at time zero, if available. - The kinetic model can alternatively be specified with a shorthand name for parent only degradation models, e.g. `SFO`, or `DFOP`. @@ -14,6 +16,8 @@ ## BUG FIXES +- In the determination of the degrees of freedom in `mkinerrmin`, formation fractions were accounted for multiple times in the case of parallel formation of metabolites. See the new feature described above for the solution. + - `transform_rates=FALSE` in `mkinfit` now also works for FOMC and HS models. - Initial values for formation fractions were not set in all cases. |
