2006-05-23Don't do calplot and lod for linear models from weightedranke18-50/+262
regression any more, since this is not supported (PR#8877). git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@13 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-16Tried to fix the return value of lod, but not yet.ranke1-1/+1

2006-05-16- Took loq and lod apart again. lod is now an implemantation of Massart, loq isranke11-68/+153
an own variant of DIN 32645 (relative error on x axis). - Partly make functions work on models where x and y are named different from "x" and "y" (loq to be done). git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@11 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-15A trial to improve the lod function, I don't really understandranke6-21/+26
the predict.lm function unfortunately git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@10 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-15Splitted the lod and loq functions. Documentation stillranke5-15/+33
must be updated git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@9 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-12- Fixed the inverse predictionranke17-55/+167
- Now I have a working approach for the calculation of LOD and LOQ, but it seems to be different from what everybody else is doing (e.g. Massart chaper 13). I like it, however. Maybe it even yields a paper. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@8 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-11- The vignette is in a publisheable stateranke16-111/+263
- In addition to the Massart examples, the sample data from dintest (DIN 32645) has been tested - inverse.predict and calplot now also work on glm objects git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@7 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-10The inverse prediction works in a variety of cases and isranke24-262/+6067
tested with Examples 7 and 8 from Massart! I need to compare with the DIN and draper examples, and finish the package vignette. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@6 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-09Added the example data, and validated it by writingranke6-4/+48
a demo producing the first four columns from Table 8.5 and the weighted regression. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@5 5fad18fb-23f0-0310-ab10-e59a3bee62b4
2006-05-09Removed the chm files, not necessary for a source package.ranke10-411/+0

2006-05-09Started a new approach, namely just adding a inverse.predictranke1-0/+40
method for univariate lm models. This will be based on Massart, p. 200. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@3 5fad18fb-23f0-0310-ab10-e59a3bee62b4
