Abstract.
Graphical chain models are a powerful tool for analyzing multivariate data. Their practical use may still be cumbersome in some respects, since fitting the model requires a lengthy selection strategy based on the calculation of an enormous number of different regressions. In this paper, we present a computer system especially designed for the calculation of graphical chain models, which will not only automatically carry out the model search but also visualize the corresponding graph at each stage of the model fit. In addition, it allows the user to modify the graph and to fit the model interactively.
