Causal graph

In statistics, econometrics, epidemiology, genetics and related disciplines, causal graphs (also known as path diagrams, causal Bayesian networks or DAGs) are probabilistic graphical models used to encode assumptions about the data-generating process.

Causal graphs can be used for communication and for inference. They are complementary to other forms of causal reasoning, for instance using causal equality notation. As communication devices, the graphs provide formal and transparent representation of the causal assumptions that researchers may wish to convey and defend. As inference tools, the graphs enable researchers to estimate effect sizes from non-experimental data,[1][2][3][4][5] derive testable implications of the assumptions encoded,[1][6][7][8] test for external validity,[9] and manage missing data[10] and selection bias.[11]

Causal graphs were first used by the geneticist Sewall Wright[12] under the rubric "path diagrams". They were later adopted by social scientists[13][14][15][16][17] and, to a lesser extent, by economists.[18] These models were initially confined to linear equations with fixed parameters. Modern developments have extended graphical models to non-parametric analysis, and thus achieved a generality and flexibility that has transformed causal analysis in computer science, epidemiology,[19] and social science.[20]
