In cluster analysis it is generally assumed that one single cluster structure is contained in a data matrix, and that this structure may be confined to a subset of the observed variables. This paper investigates a new solution that simultaneously selects the relevant variables and discovers multiple cluster structures from possibly dependent subsets of variables. The basic idea is to recast the problem as a model comparison problem in which conditional independence assumptions are introduced using multivariate regression models with correlated and non-normal error terms. A stepwise procedure for selecting a locally optimal model is also proposed. Results obtained from a Monte Carlo study are briefly described
