| Description | The paper presents an Markov Chain Monte Carlo algorithm for both variable and covariance selection in the context of logistic mixed eects,models. This algorithm allows us to sample solely from stan- dard densities, with no additional tuning being needed. We apply a stochastic search variable approach to select explanatory variables as well as to determine the structure of the random eects,covariance matrix. For logistic mixed eects,models prior determination of explanatory variables and random eects,is no longer prerequisite since the definite structure is chosen in a data-driven manner in the course of the model- ing procedure. As an illustration two real-data examples from finance and tourism studies are given.
