An application of the linear discriminant function and a multivariate analysis to caddis larvae taxonomy

Conference paper


Computer programs are used for the discrimination of two related species R. dorsalis and R. vulgaris (Rhyacophilidae, Trichoptera). One program is a discriminant analysis for two groups, including the calculation of the coefficients for a linear discriminant function with which an unknown individual can be allocated to one or other species. A second program represents a multiple discriminant analysis in a stepwise manner by entered and removed variables. Fourteen measurements originating in the head were used, from which 4 variables were needed for the first program and 5 other variables for the second program.
