ON THE EXISTENCE OF THE MAXIMUM LIKELIHOOD ESTIMATES IN LOGISTIC DISCRIMINANT ANALYSIS
Abstract:In this paper,investigation is conducted of the problem of existence and uniqueness of the maximum likelihood estimates in logistic discriminant analysis, which is a very difficult problem and can occur in practice. Proofs of the assertions in the completed sepatate and overlapped data situation are given.
