Constructor Details

McGetNumTestsH0

public McGetNumTestsH0(IndependenceWrapper independenceWrapper,
 ConditioningSetType conditioningSetType)

Calculates the number of tests for the Markov check of whether the p-values for the estimated graph are distributed as U(0, 1).

Parameters:

independenceWrapper - An instance of IndependenceWrapper used to encapsulate and perform independence tests on the dataset with specific configurations.

conditioningSetType - The type of conditioning set employed during Markov checks, represented by the ConditioningSetType enum; this dictates how variables are conditioned in independence tests.

Method Details

getAbbreviation

public String getAbbreviation()

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

Specified by:

getAbbreviation in interface Statistic

Returns:

The abbreviation for the statistic.

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:

The description of the statistic.

getValue

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

Calculates the number of tests done under the null hypothesis of independence for the Markov check of whether the p-values for the estimated graph are distributed as U(0, 1).

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.

parameters - The parameters

Returns:

The Anderson Darling P value.

Throws:

IllegalArgumentException - if the data model is null.

getNormValue

public double getNormValue(double value)

Calculates the normalized value of a statistic.

Specified by:

getNormValue in interface Statistic

Parameters:

value - The value of the statistic.

Returns:

The normalized value of the statistic.
