quantchem: Quantitative chemical analysis: calibration and evaluation of
results
Statistical evaluation of calibration curves by different
regression techniques: ordinary, weighted, robust (up to 4th
order polynomial). Log-log and Box-Cox transform, estimation of
optimal power and weighting scheme. Tests for heteroscedascity
and normality of residuals. Different kinds of plots commonly
used in illustrating calibrations. Easy "inverse prediction" of
concentration by given responses and statistical evaluation of
results (comparison of precision and accuracy by common tests).
