Class HybridCgCutpoints

java.lang.Object

edu.cmu.tetrad.hybridcg.HybridCgCutpoints

public final class HybridCgCutpoints
extends Object

Utilities to populate HybridCgPm cutpoints for discrete children that have continuous parents. Cutpoints are computed from a DataSet using either equal-interval or equal-frequency rules.

public static void setAll(HybridCgModel.HybridCgPm pm,
 DataSet data,
 int bins,
 HybridCgCutpoints.Method method)

For every DISCRETE child Y with ≥1 continuous parent, computes and installs cutpoints for each continuous parent using the chosen method and desired number of bins.

Parameters:

pm - existing HybridCgPm (unchanged except where cutpoints are set)

data - DataSet whose columns match pm.getNodes() (names)

bins - desired number of bins per continuous parent (>=2 → bins-1 cutpoints)

method - equal-intervals or equal-frequency
