Interface TetradTest

All Known Implementing Classes:

TetradTestContinuous, TetradTestDiscrete, TetradTestPopulation

public interface TetradTest

Provides an interface for classes that test tetrad constraints. For the continuous case, we have a variety of tests, including a distribution-free one (which may not be currently practical when the number of variables is too large).
