Class IndTestMixedMultipleTTest

java.lang.Object
edu.cmu.tetrad.search.work_in_progress.IndTestMixedMultipleTTest
All Implemented Interfaces:
IndependenceTest
public class IndTestMixedMultipleTTest extends Object implements IndependenceTest
Performs a test of conditional independence X _||_ Y | Z1...Zn where all searchVariables are either continuous or discrete. This test is valid for both ordinal and non-ordinal discrete searchVariables.

This logisticRegression makes multiple assumptions: 1. IIA 2. Large sample size (multiple regressions needed on subsets of sample)
