Hello, I'm looking for a metric which indicates the distance/ separability between two classes (e.g. two normal distributions with a known mean and known cov. matrix). Currently I use the bhattacharyya distance but maybe there are other distance metrics for classes/clusters I can try? thanks, best regards ------------------------------------------- J.C.
