Titterington, D. M. An alternative stochastic supervisor in discriminant analysis. (English) Zbl 0665.62063 Pattern Recognition 22, No. 1, 91-95 (1989). Suggested is a model for a stochastic supervisor that is an alternative to the model proposed for the 2-group case, by T. Krishnan and S. C. Nandy [ibid. 20, 379-384 (1987; Zbl 0625.62043)]. The model uses a logistic-normal distribution for the classification variable and this results in a simple EM algorithm for parameter estimation. Illustrative comparisons are provided and generalizations are discussed.
