Nothing
A port of the webbased software 'DAGitty', available at <http://dagitty.net>, for analyzing structural causal models (also known as directed acyclic graphs or DAGs). This package computes covariate adjustment sets for estimating causal effects, enumerates instrumental variables, derives testable implications (dseparation and vanishing tetrads), generates equivalent models, and includes a simple facility for data simulation.
