Some Computational Aspects of Graphical Model Selection
David Edwards · Contributions to statistics · 1993
Two alternative approaches to graphical model selection — stepwise edge elimination, and a so-called fast method proposed by Edwards and Havránek (1985, 1987) — are described and compared. Some emphasis is given to specific non — numerical computational aspects: in particular, an efficient algorithm for the dual representation problem is described. The model selection methods are applied to a contingency table concerning risk factors for coronary heart disease.
