On the identifiability of finite mixtures
Webfor finite mixtures to be identifiable and what kind of distributions family which is identifiable. Key words: Finite mixture, identifiable. 1. Introduction The purposes of this paper are to collect results concerning identi-fiability of finite mixtures which are scattered in several journals and books, and to present them as coherent as ... WebBy the theorem, for fixed p the class of G(n)-mixtures of 5Y = (F(x; n, p)j is identifiable. However, when n is fixed, the class of G(p)-mixtures of 5Y is not identifiable.7 I Comparable statements apply for other choices of W:. The crucial points appear to be (i) all distributions having essentially the same finite spectrum (ii) the functional ...
