Class Dci

java.lang.Object

edu.cmu.tetrad.search.work_in_progress.Dci

public class Dci
extends Object

Implements the DCI (Distributed Causal Inference) algorithm for learning causal structure over a set of variable from multiple datasets that each may only measure proper overlapping subsets of that sets, or datasets with some variables in common and others not. The algorithm currently takes as input a set of PAGs (presumably learned using a local learning algorithm such as FCI) and returns a complete set of PAGs over every variable included a dataset that are consistent with all the PAGs (same d-separations and d-connections)
