Location-Scale Models: Variability as an Outcome

In this chapterwithin-person variability as a construct; the mixed-effects location-scale model with submodels for the mean, the between-person variance, and the within-person variance, and a random scale effect; the model in three views and as a unified model graph; estimation by quadrature, the Laplace approximation, and Markov chain Monte Carlo; the Riesby depression data and a simulated experience-sampling study; a simulation on the number of occasions needed; extensions and reporting.
