chemCal/demo, branch main Calibration functions for analytical chemistry (also on github) https://cgit.jrwb.de/chemCal/atom?h=main 2006-06-23T15:33:27Z - inverse.predict now has a var.s argument instead of the never 2006-06-23T15:33:27Z ranke ranke@5fad18fb-23f0-0310-ab10-e59a3bee62b4 2006-06-23T15:33:27Z urn:sha1:9e0dae397df8c18e7333d2604cae96b2a7927420 tested ss argument. This is documented in the updated vignette - loq() now has w.loq and var.loq arguments, and stops with a message if neither are specified and the model has weights. - calplot doesn't stop any more for weighted regression models, but only refrains from drawing prediction bands - Added method = "din" to lod(), now that I actually have it (DIN 32645) and was able to see which approximation is used therein. - removed the demos, as the examples and tests are already partially duplicated - The vignette is more of a collection of various notes, but should certainly be helpful for the user. - Version bump to 0.1-xxx git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@16 5fad18fb-23f0-0310-ab10-e59a3bee62b4 First version published on my website. 2006-05-23T15:24:58Z ranke ranke@5fad18fb-23f0-0310-ab10-e59a3bee62b4 2006-05-23T15:24:58Z urn:sha1:3b3d6dfc88c4b8b6475147a3afb5258a5fc82fa5 git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@14 5fad18fb-23f0-0310-ab10-e59a3bee62b4 - Fixed the inverse prediction 2006-05-12T21:59:33Z ranke ranke@5fad18fb-23f0-0310-ab10-e59a3bee62b4 2006-05-12T21:59:33Z urn:sha1:69504b635d388507bce650c44b3bfe17cad3383e - 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 The inverse prediction works in a variety of cases and is 2006-05-10T15:44:14Z ranke ranke@5fad18fb-23f0-0310-ab10-e59a3bee62b4 2006-05-10T15:44:14Z urn:sha1:513dfbdcdda94a901b5901b486ff5500c7d158b1 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 Added the example data, and validated it by writing 2006-05-09T20:28:46Z ranke ranke@5fad18fb-23f0-0310-ab10-e59a3bee62b4 2006-05-09T20:28:46Z urn:sha1:8d30b2cd951c992e4f9aa3055054091e18b8b4f0 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
