Class Ion

java.lang.Object
edu.cmu.tetrad.search.work_in_progress.Ion
public class Ion extends Object
Implements the ION (Integration of Overlapping Networks) algorithm for distributed causal inference. The algorithm takes as input a set of PAGs (presumably learned using a local learning algorithm) over variable sets that may have some variables in common and others not in common. The algorithm returns a complete set of PAGs over every variable form an input PAG_of_the_true_DAG that are consistent (same d-separations and d-connections) with every input PAG_of_the_true_DAG.
