(2007): Optimal species distinction by discriminant analysis: comparing established methods of character selection with a combination precedure using ant morphometrics as a case study
J ZOOL SYST EVOL RES, 45, 82-87; ISSN 0947-5745 FullText FullText_BOKU

We compare the performances of established means of character selection for discriminant analysis in species distinction with a combination procedure for finding the optimal character combination (minimum classification error, minimum number of required characters), using morphometric data sets from the ant genera Cardiocondyla, Lasius and Tetramorium. The established methods are empirical character selection as well as forward selection, backward elimination and stepwise selection of discriminant analysis. The combination procedure is clearly superior to the established methods of character selection, and is widely applicable.
