Mixture Models

This chapter covers a class of models where a rather simple distribution is made more complex and less informative by a mechanism that mixes together several known or unknown distributions. This representation is naturally called a mixture of distributions, as illustrated above. Inference about the parameters of the elements of the mixtures and the weights is called mixture estimation, while recovery of the original distribution of each observation is called classification (or, more exactly, unsupervised classification to distinguish it from the supervised classification to be discussed in Chap. 8).
