JSM '00, August 13-17, 2000, Indianapolis, Indiana, USA SESSION TITLE: Consistent Estimation of Mixture Complexity SESSION DESCRIPTION: The consistent estimation of mixture complexity is of fundamental importance in nearly all applications of finite mixture models. An enormous body of literature exists on the application, computational issues, and theoretical aspects of mixture models when the number of components is known, but only recently has significant progress been made on estimating the unknown number of components. The objectives of this proposed session are two-fold: to bring together numerous researchers active in the area and present a sampling of the newest results, and to introduce mixture model practitioners to the available theory and methods. The relevance of the proposed session to the JSM 2000 theme stems from the fact that mixture models are routinely employed across the entire diverse application range of statistics, including nearly all of the social and experimental sciences.
