Abstract

Abstract : This paper discusses local structure recovery of chain graphs (CGs) when there exist unobserved or latent variables or after marginalization over observed variables. Under a condition presented in this paper, it is explained which edges and directions of edges in local structure can be recovered validly and which cannot after marginalization.
