Abstract

This paper studies the problem of estimating the number of clusters in the context of logistic regression clustering. The classi.cation likelihood approach is employed to tackle this problem. An information theoretic criterion for selecting the number of logistic curves is proposed in the sequel and then its asymptotic property is considered. The paper is arranged as follows: In Section 2, some notations are given and an information theoretic criterion is proposed for estimating the number of clusters. In Section 3, the small sample performance of the proposed criterion is studied by Monte Carlo simulation. In Section 4, the asymptotic property of the criterion proposed in Section 2 is investigated. Some lemmas needed in Section 4 are given in the appendix.
