Local Structure Recovery of Chain Graphs after Marginalization
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 va...

| description | 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. |
