When distributing These slides present an introduction to graphs for causal relationships. A directed graph is said to be weakly connected (or, more simply, connected) if the corresponding undirected graph (where directed edges u!vand/or v!u are replaced with a single undirected edge fu;vgis connected. We give an algebraic presentation of directed acyclic graph structure, introducing a symmetric monoidal equational theory whose free PROP we characterise as that of nite abstract dags with input/output interfaces. Collider: a vertex on a path with two incoming arrows. They capture key con-cepts used in analyzing task scheduling and concurrency control. For our purposes, each vertex i is a parent of j and j is a child of i; j; ch(i) is the set of children of i. Directed acyclic graphs (DAGs) present all the paths from a causal variable D to outcome Y, including the role of any intermediate variables. The introduction here is very brief. Our development provides an initial-algebra semantics for dag structure Path: an acyclic sequence of adjacent nodes. For example, the graph in Figure is weakly connectedDAGs Nonparametric Structural Equation Models (NPSEM) Equivalence to the nonparametric structural equation models: X U So, the direct prerequisite graph among subjects had better be acyclic: Definition A directed acyclic graph (DAG) is a directed graph with no cy-cles. A cycle is directed if it contains a directed edge. Collider: a vertex on a Directed Acyclic Graphs Backdoor Path and Confounder We are interested in the causal e⁄ect of D on Y: D! Y. A backdoor path is a variable that a⁄ects both D and Y D! Y% X Abstract. causal path: all arrows pointing out of i and into j non-causal path: some arrows going against causal order. causal path: all arrows pointing out of i and into j non-causal path: some arrows going against causal order. = j. DAGs have particular importance in computer science. i → a1 → · · · → an−1 → j. So, the direct prerequisite graph among subjects had better be acyclic: Definition A directed acyclic graph (DAG) is a directed graph with no cy-cles. For more detail see I Cunningham (), chapter 3, provides a good introduction Figure Anode directed acyclic graph (DAG). DAG: (i) all edges are directed; Path: an acyclic sequence of adjacent nodes.
