Package edu.cmu.tetrad.algcomparison.statistic

Class FractionDependentUnderAlternative

java.lang.Object

edu.cmu.tetrad.algcomparison.statistic.FractionDependentUnderAlternative

All Implemented Interfaces:

Statistic, Serializable

public class FractionDependentUnderAlternative
extends Object
implements Statistic

Estimates whether the p-values under the null are Uniform usign the Markov Checker. This estimate the fraction of dependent judgements from the local Fraithfulness check, under the alternative hypothesis of dependence. This is only applicable to continuous data and really strictly only for Gaussian data.

Constructor Details

FractionDependentUnderAlternative

public FractionDependentUnderAlternative()

Constructor for FractionDependentUnderAlternative.

FractionDependentUnderAlternative

public FractionDependentUnderAlternative(double alpha)

Constructor for FractionDependentUnderAlternative.

Parameters:

alpha - a double

Method Details

getAbbreviation

public String getAbbreviation()

The abbreviation for the statistic. This will be printed at the top of each column.

Specified by:

getAbbreviation in interface Statistic

Returns:

This abbreviation.

getDescription

public String getDescription()

Returns a short one-line description of this statistic. This will be printed at the beginning of the report.

Specified by:

getDescription in interface Statistic

Returns:

This description.

getValue

public double getValue(Graph trueGraph,
 Graph estGraph,
 DataModel dataModel,
 Parameters parameters)

Returns the value of this statistic, given the true graph and the estimated graph.

Specified by:

getValue in interface Statistic

Parameters:

trueGraph - The true graph (DAG, CPDAG, PAG_of_the_true_DAG).

estGraph - The estimated graph (same type).

dataModel - The data model (can be null).

parameters - The parameters (can be null).

Returns:

The value of the statistic.

getNormValue

public double getNormValue(double value)

Returns a mapping of the statistic to the interval [0, 1], with higher being better. This is used for a calculation of a utility for an algorithm. If the statistic is already between 0 and 1, you can just return the statistic.

Specified by:

getNormValue in interface Statistic

Parameters:

value - The value of the statistic.

Returns:

The weight of the statistic, 0 to 1, higher is better.

setAlpha

public void setAlpha(double alpha)

Setter for the field alpha.

Parameters:

alpha - a double
