Il problema della riduzione del numero di parametri nell'analisi discriminante

C. Perna
In this paper we discuss a statistical procedure for reducing the number of parameters to be estimated in the quadratic discriminant function. This procedure is based on the specification of relationships between covariance matrices of the populations. In the problem of discrimination between two populations, we have considered two particular relationships: the first specifies a common principal components model and the second equal correlation matrices. After a brief review of the methods, we compare the...
