Julia package for causal inference, graphical models and structure learning with the PC algorithm. This package contains for now the classical PC algorithm, tested on random DAGs by comparing the result of the PC algorithm using the d-separation oracle with CPDAGs computed with Chickering's DAG->CPDAG conversion algorithm (implemented as dsep and cpdag in this package).
See the documentation for other implemented functionality and issue #1 (Roadmap/Contribution) for coordination of the development.
The algorithms use the Julia package LightGraphs. Graphs are represented by sorted adjacency lists (vectors in the implemention). CPDAGs are just DiGraphs where unoriented edges are represented by both a forward and a backward directed edge.
