Class RandomGraph.UniformGraphGenerator

java.lang.Object
edu.cmu.tetrad.graph.RandomGraph.UniformGraphGenerator
Enclosing class:
RandomGraph
public static final class RandomGraph.UniformGraphGenerator extends Object
Generates random DAGs uniformly with certain classes of DAGs using variants of Markov chain algorithm by Malancon, Dutour, and Philippe.
