Abstract
We present in this paper a methodology to deal with heterogeneity in modelling when the sources are unknown. Although the approach is general we present it for the PLS-PM latent variable modelling. We call such approach PATHMOX. The idea behind PATHMOX is to build a path models tree having a binary decision tree look-alike structure with models for different segments in each of its nodes. The split criterion consists in an F statistic for comparing structural models based on testing the equality...
