To assess the fit provided bymixture models with different numbers of components, the BIC (BayesianInformation Criterion) is used [<A HREF="node23.html#FR98hmc">5</A>]. The aim of this example is notto promote the use of BIC for selecting the number of component in a mixturemodel (see the comments in <code>ex_bix</code> concerning the sensitivity of theprocedure to various parameters of the analysis) but rather to illustrate theuse of <TT>H2M</TT> functions in a more ``realistic'' setting.<P><BR><HR><ADDRESS>Olivier Cappé, Aug 24 2001</ADDRESS></BODY></HTML>
