More specifically, we present an alternative use of a latent variable version of the Mixture Transition Distribution (MTD) model, which allows for clustering of continuous longitudinal data, called the Hidden MTD (HMTD) model. We compare the HMTD and its clustering performance to the popular Growth Mixture Model (GMM), as well as to the recently introduced GMM based on individual case residuals (ICR-GMM). The GMM and the ICR-GMM contrast with HMTD, because they are based on an explicit change function describing the individual sequences on the dependent variable (here, we implement a non-linear exponential change function). This paper has three objectives. First, it introduces the HMTD. Second, we present the GMM and the ICR-GMM and compare them to the HMTD. Finally, we apply the three models and comment on how the conclusions differ depending on the clustering model, when using a specific dataset in psychology, which is characterized by a small number of sequences (n = 102), but that are relatively long (for the domains of psychology and social sciences: t = 20). We use data from a learning experiment, in which healthy adults (19-80 years old) were asked to perform a perceptual-motor skills over 20 trials.</p> Dewey 150 108 Section de psychologie 71 false 599 Méthodologie et analyse des données (MAD) Symmetry 12 10 82c4f38d-2230-451c-b094-c1c8aebfd106 Article (Published version) Public Article-scientifique-from-unpaywall.pdf 932901 application/pdf CC BY openAccess Faculté de psychologie et des sciences de l'éducation / Section de psychologie
