Enum Class Fask.LeftRight

java.lang.Object

java.lang.Enum<Fask.LeftRight>

edu.cmu.tetrad.search.Fask.LeftRight

All Implemented Interfaces:

Serializable, Comparable<Fask.LeftRight>, Constable

Enclosing class:

Fask

public static enum Fask.LeftRight
extends Enum<Fask.LeftRight>

Enumerates the options left-right rules to use for FASK. Options include the FASK left-right rule and three left-right rules from the Hyvarinen and Smith pairwise orientation paper: Robust Skew, Skew, and Tanh. In that paper, "empirical" versions were given in which the variables are multiplied through by the signs of the skewnesses; we follow this advice here (with good results). These others are provided for those who prefer them.
