Interactive analysis of high-dimensional association structures with graphical models

Graphical chain models are a capable tool for analyzing
multivariate data. However, their practical use may still be
cumbersome in some respect since fitting the model requires the
application of an intensive 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 is not only planned to
automatically carry out the model search but also to visualize the
corresponding graph at each stage of the model fit on request by
the user. It additionally allows to modify the graph and the model
fit interactively.
