AdjacencyTn

public AdjacencyTn()

Constructs the statistic.

Method Details

getAbbreviation

public String getAbbreviation()

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

Returns the name of the statistic.

Specified by:

getAbbreviation in interface Statistic

Returns:

Thsi abbreviation.

getDescription

public String getDescription()

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

Returns the description of the statistic.

Specified by:

getDescription in interface Statistic

Returns:

This description.

getValue

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

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

Returns the value of the 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.

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.

Returns a mapping of the statistic to the interval [0, 1], with higher being better. This is used for a

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.
