Dear R-helpers     I am having problem or reservation analyzing my data using discrminant analysis. The problem is that all my dependent variables are categorical which means that the normalty assumption is no longer valid. Can one still use discrminant analysis for such dat

Re: [R] discriminant analysis

Which kind of discriminant analysis? If you mean LDA, use lda() in package MASS and read the correpsonding book "Modern Applied Statistics with S" by Venables and Ripley published by Springer. Uwe Ligges On 01.06.2010 09:24, suman dhara wrote: Sir, Can you suggest some function for discrim
