图模型马尔可夫等价类的一些模拟结果
Some simulation results of Markov equivalence classes
有向无环图和完全的部分有向图常被用来表示因果网络和等价的马尔可夫等价图模型。所有马尔可夫等价图构成了图模型空间。本文通过模拟方法研究了该模型空间的性质。
irected acyclic graphs (DAGs) and completed partial directed acyclic graphs (CPDAG) are widely used to represent causal systems or uncertain probability systems. Some studies about small graphs with dozens of nodes have shown that given the number of nodes, p, in average, each CPDAG encode about 3.7 DAGs. In this paper, we analyze the properties of CPDAGs with large dimensions and sparsity settings via MCMC approach.
