Stable Mixed Graphs

  title={Stable Mixed Graphs},
  author={Kayvan Sadeghi},
In this paper we study classes of graphs with three types of edges that capture the modified independence structure of a directed acyclic graph (DAG) after marginalisation over unobserved variables and conditioning on selection variables using the m-separation criterion. These include MC, summary, and ancestral graphs. As a modification of MC graphs we define the class of ribbonless graphs (RGs) that permits the use of the m-separation criterion. RGs contain summary and ancestral graphs asโ€ฆย CONTINUE READING
