<br/><br/> This thesis concentrates on the hypothesis testing and information criteria approaches for assessing the number of components in a  nite mixture of Birnbaum-Saunders (BS) distributions. Initially, the identi ability for a g-component mixture of BS distributions is proved and the expectation
