The mining of association rules can provide relevant and novel information to the data analyst. However, current techniques do not take into account that the observed associations may arise from variables that are unrecorded in the database. For instance, the pattern of answers in a large marketing survey might be better explained by a few latent traits of the population than by direct association among measured items. Techniques for mining association rules with hidden variables are still largely unexplored. This paper provides a sound methodology for finding association rules of the type
