Introduction These slides present an introduction to graphs for causal relationships. Directed acyclic graphs (DAGs) present all the paths from a causal variable D to outcome Y, including …
This article explains how to construct, interpret, and present directed acyclic graphs as part of clinical research studies and how they can help communicate a study’s strengths or limitations.
Enumeration of labeled acyclic digraphs Corollary 1.3, when combined with a result of Read (also obtained by Bender and Goldman), yields an immediate solution to the problem of …
Definition (acyclic, forest, DAG) German: azyklisch/kreisfrei, Wald, DAG A graph or digraph G is called acyclic if there exists no cycle in G. An acyclic graph is also called a forest. An acyclic …

Directed acyclic graphs (DAGs) are an intuitive yet rigorous tool to communicate about causal questions in clinical and epidemiologic research and inform study design and statistical analysis.
Let AO(G) be the set of acyclic orientations of G, and Col(G) the set of proper colourings of G (with an arbitrary number of colours, but the colours are ordered and all of them are used). We …
