Dear R-users,
I have problem or at cross-road on using discrminant
analysis for my set of data. All my dependent variables are all categorical,
hence the normalty assumption is no longer valid. Is it still right to use
discrminant analysis or is there any non-parametric technique or approach to
discriminant analysis?
Discriminant analysis is not necessarily based on a certain distribution assumption, the "Fisher" approach is only based on the assumption of similar covariance within classes. Anyway, it does not make much sense with categorical variables, why not start with a tree, for example. Uwe Ligges
