2019-06-04Fix a bug introduced in the last commitJohannes Ranke1-2/+4
2019-06-04For the d_3 algorithm, report which was better, if anyJohannes Ranke1-2/+13
2019-06-04Additional algorithm "d_c", more tests, docsJohannes Ranke1-46/+71
The new algorithm tries direct optimization of the likelihood, as well as a three step procedure. In this way, we consistently get the model with the highest likelihood for SFO, DFOP and HS for all 12 new test datasets.
2019-06-04Algorithms direct, two-, three-, fourstep, IRLSJohannes Ranke1-9/+41
All of them are working now and allow for comparison Based on SFO, DFOP and HS fits to twelve test datasets, only the combination of direct and threestep is needed to find the lowest AIC
2019-06-03Status von Samstag morgen - untestedJohannes Ranke1-37/+63

2019-05-20Only use colors for error model "obs"Johannes Ranke1-3/+3
2019-05-08Add functionality to plot the error modelJohannes Ranke4-15/+116

Static documentation rebuilt by pkgdown
2019-05-07After the OLS step, use OLS parameter estimatesJohannes Ranke1-24/+24
- Fix the respective error in the code - Static documentation rebuilt by pkgdown
2019-05-03Improve error model fittingJohannes Ranke2-15/+36
Now we have a three stage fitting process for nonconstant error models: - Unweighted least squares - Only optimize the error model - Optimize both Static documentation rebuilt by pkgdown
2019-05-02Better initials for error model parametersJohannes Ranke1-8/+21
- Also make it possible to specify initial values for error model parameters. - Run tests - Rebuild docs
2019-04-24Improve output and update testsJohannes Ranke1-5/+9
Remove skipped tests as I do not intend to reactivate them
2019-04-10Address failure on travisJohannes Ranke1-1/+1
Also reduce the digits in the representative half-live given by nafta()
2019-04-10Adapt tests, vignettes and examplesJohannes Ranke3-68/+90
- Write the NEWS - Static documentation rebuilt by pkgdown - Adapt mkinerrmin - Fix (hopefully all) remaining problems in mkinfit
2019-04-08Remove zero observations, adapt logLikJohannes Ranke2-24/+11
Zero observations at time zero made fitting the two-component error model fail. A concentration of exactly zero does not make sense anyways, as we generally have a limit of detection
2019-04-05Report negative log-likelihood during fitsJohannes Ranke1-4/+10
If not quiet = TRUE
2019-04-04Direct error model fitting worksJohannes Ranke1-366/+133
- No IRLS required - Removed optimization algorithms other than Port - Removed the dependency on FME - Fitting the error model 'obs' is much faster for the FOCUS_2006_D dataset and the FOMC_SFO model (1 second versus 3.4 seconds) - Vignettes build slower. Compiled models needs 3 minutes instead of 1.5 - For other vignettes, the trend is less clear. Some fits are faster, even for error_model = "const". FOCUS_Z is faster (34.9 s versus 44.1 s) - Standard errors and confidence intervals are slightly smaller - Removed code for plotting during the fit, as I hardly ever used it - Merged the two cost functions (using transformed and untransformed parameters) into one log-likelihood function
2019-03-04signif for DTx when printing nafta resultsJohannes Ranke1-1/+1
In order to be able to test cross-platform

2018-07-18Correct references to the Rocke and Lorenzato modelJohannes Ranke3-6/+6
Rename 'sigma_rl' to 'sigma_twocomp' as the Rocke and Lorenzato model assumes lognormal distribution for large y. Rebuild static documentation.
