Enum Class FfDmlContinuous.Channel

java.lang.Object

java.lang.Enum<FfDmlContinuous.Channel>

edu.cmu.tetrad.search.score.FfDmlContinuous.Channel

All Implemented Interfaces:

Serializable, Comparable<FfDmlContinuous.Channel>, Constable

Enclosing class:

FfDmlContinuous

public static enum FfDmlContinuous.Channel
extends Enum<FfDmlContinuous.Channel>

Response channels for the distributional score. Each is an orthogonal transform of the (globally z-scored) child column; the local score is the weighted sum of per-channel GP log marginal likelihoods against the shared parent features. MEAN alone reproduces FF-ML; adding higher channels buys sensitivity to conditional variance / skew / tail dependence.

Enum Constant Summary

Enum Constants

Enum Constant	Description
KURT	He4(Y)/sqrt(4!) = (Y^4-6Y^2+3)/sqrt(24): conditional-kurtosis / tail channel.
MEAN	He1(Y) = Y: conditional-mean channel.
RANK	Normal-scored ranks of Y: rank-robust omnibus channel (CORD-style).
SKEW	He3(Y)/sqrt(3!) = (Y^3-3Y)/sqrt(6): conditional-skew channel.
VAR	He2(Y)/sqrt(2!) = (Y^2-1)/sqrt(2): conditional-variance / co-volatility channel.

Method Summary

Modifier and Type	Method	Description
static FfDmlContinuous.Channel	valueOf(String name)	Returns the enum constant of this class with the specified name.
static FfDmlContinuous.Channel[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

MEAN

public static final FfDmlContinuous.Channel MEAN

He1(Y) = Y: conditional-mean channel. Reproduces FF-ML exactly.

VAR

public static final FfDmlContinuous.Channel VAR

He2(Y)/sqrt(2!) = (Y^2-1)/sqrt(2): conditional-variance / co-volatility channel.

SKEW

public static final FfDmlContinuous.Channel SKEW

He3(Y)/sqrt(3!) = (Y^3-3Y)/sqrt(6): conditional-skew channel.

KURT

public static final FfDmlContinuous.Channel KURT

He4(Y)/sqrt(4!) = (Y^4-6Y^2+3)/sqrt(24): conditional-kurtosis / tail channel.

RANK

public static final FfDmlContinuous.Channel RANK

Normal-scored ranks of Y: rank-robust omnibus channel (CORD-style).

Method Details

values

public static FfDmlContinuous.Channel[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static FfDmlContinuous.Channel valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
