      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 ...
    • The Pathmox approach for PLS path modeling segmentation 

      Lamberti, Giuseppe; Aluja Banet, Tomàs; Sanchez, Gaston (2016-08)
      Article
      Open Access
      Modeling has often failed to meet expectations, mostly because of the difficulty of comprehending relationships within phenomena and expressing them in mathematical models. Reality is frequently too complex to be reflected ...
    • The Pathmox approach for PLS path modeling: discovering which constructs differentiate segments

      Article
      Open Access
      The problem of heterogeneity represents a very important issue in the decision-making process. Furthermore, it has become common practice in the context of marketing research to assume that different population parameters ...
