edu.cmu.tetrad.algcomparison.statistic.MarkovCheckKsPassesBestOf10

All Implemented Interfaces:

Statistic, Serializable

public class MarkovCheckKsPassesBestOf10
extends Object
implements Statistic

Represents a markov check statistic that calculates the Kolmogorov-Smirnoff P value for whether the p-values for the estimated graph are distributed as U(0, 1). This version reports whether the p-value is greater than 0.05 and reports the best of 10 repetitions.

MarkovCheckKsPassesBestOf10

public MarkovCheckKsPassesBestOf10()

Calculates the Kolmogorov-Smirnoff P value for the Markov check of whether the p-values for the estimated graph are distributed as U(0, 1).

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)

Calculates whether Kolmogorov-Smirnoff P > 0.05.

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.

Returns:

1 if p > 0.05, 0 if not.

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.
