By default, the number of mixture components is estimated from data. Number of components may be also provided as second parameter or in the 'comp' option. SDMIXTURE may be used for unsupervised cluster analysis using the 'cluster' option. If specified, SDMIXTURE will perform mixture estimation on each class present and return one output per cluster.
