I have tried this with my actual data, and everything works smoothly, including the monotonically decreasing error rates. e.g.: formula Error 1 Cr 0.4167 2 Cr + Mg 0.1667

Hello R list, I'm looking to do some stepwise discriminant function analysis (DFA) based on the minimization of Wilks' lambda in R to end up with a composite signature (of metals "Al","Sb","Bi","Cr","Ba") capable of discriminating 100% of the source factors (LANDUSE: "A","B","C"). The Wilks' lamb
