BidirectedLatentPrecision

public BidirectedLatentPrecision()

The BidirectedLatentPrecision class implements the Statistic interface and represents a statistic that calculates the percentage of bidirected edges in an estimated graph for which a latent confounder exists in the true graph.

Method Details

getAbbreviation

public String getAbbreviation()

Returns the abbreviation for the statistic. The abbreviation is a short string that represents the statistic. For this statistic, the abbreviation is "<->-Lat-Prec".

Specified by:

getAbbreviation in interface Statistic

Returns:

The abbreviation for the statistic.

getDescription

public String getDescription()

Returns a short description of the statistic, which is the percentage of bidirected edges for which a latent confounder exists.

Specified by:

getDescription in interface Statistic

Returns:

The description of the statistic.

getValue

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

Calculates the percentage of correctly identified bidirected edges in an estimated graph for which a latent confounder exists in the true 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.

Returns:

The percentage of correctly identified bidirected edges.

getNormValue

public double getNormValue(double value)

Calculates the normalized value of a given statistic value.

Specified by:

getNormValue in interface Statistic

Parameters:

value - The value of the statistic.

Returns:

The normalized value of the statistic.
