Graphical Methods of Structural Relations between Variables and their Application to Russian Regions (Part Two)

The second part of the article continues studying the structure of a set of variables. It consists of two pieces: (1) de-scription of a modification of Dempster covariance selection algorithm based on its combination with that of tree dependence structures construction, simulation results, methods of representation of the graphical model on the plane, and different methods of results interpretation; (2) application of the method to studying and comparing Russian regions
