Merge to Directed Acyclic Graph
The term Causal Graph appears to denote in narrower subject areas what is more generally known as the Directed Acyclic Graph. It is striking for me as a reader to find no mention or reference to Directed Acyclic Graphs in this article. It would make more sense to me if these terms were used interchangeably, thereby combining clear and precise physical intuition with the rigour of mathematical description. Of course, we are here not to change things, but to simply document them. Therefore, I appeal to experts in the respective subject areas to consider merging the articles, or, at the very least, editing this article to reflect that it refers to a subject-specific application of the concept known as the Directed Acyclic Graph.

 * Incorrect. It denotes a graphical model, which is not just a graph, but a piece of information that describes both a graph and a probability distribution. And the illustrations in this article include bidirectional arrows, making it very clear that the graphs described in this article are not intended to be restricted to directed and acyclic graphs. Therefore, I oppose this proposed merge. —David Eppstein (talk) 21:42, 20 November 2019 (UTC)
 * I agree with DE -- possibly this article should include some reference to the article directed acyclic graph, but they are not the same thing and it doesn't seem natural to cover this kind of model at that article. --JBL (talk) 01:39, 21 November 2019 (UTC)
 * I find your arguments convincing, although it was easy for me to initially overlook the difference DE pointed at. I see that Wikipedia guidelines suggest allowing one week for the discussion, so I guess, I am not supposed to retract the merge proposal template at this time.

 * Incorret (denotes a graphical model not just a graph). Suggestion: merge with Bayesian network. Krauss (talk) 21:33, 30 November 2019 (UTC)

Merge to Bayesian network
The term Causal Graph appears to denote the same general concept as Bayesian network. Krauss (talk) 21:37, 30 November 2019 (UTC)
 * I removed the merge template for what I proposed. Please place a new one for the new merger proposal. See Template:Merge Regards, AVM2019 (talk) 06:47, 8 December 2019 (UTC)
 * I removed the merge template that proposed merging Causal model with Bayesian network/Causal graph, because already explains the relation between Causal model and the subtopic of Bayesian networks in a way that does not appear to justify merging them. I left the merge template that proposed merging Bayesian network with Causal graph, as that merge appears justified. Biogeographist (talk) 17:28, 20 March 2020 (UTC)
 * No, they are not formally the same concepts. One can construct Causal Graph without invoking Bayesian Networks. Hence, I am not in favour of merging. --mcyp (talk) 07:31, 28 December 2020 (UTC)
