public class Ftfc
extends Object

Generalized Find Factor Clusters (GFFC). This generalized FOFC and FTFC to first find clusters using pure 2-tads (pure tetrads) and then clusters using pure 3-tads (pure sextads) out of the remaining variables. We do not use an n-tad test here since we need to check rank, so we will check rank directly. (This is equivqalent to using the CCA n-tad test.)

Constructor Details

Ftfc

public Ftfc(DataSet dataSet,
 double alpha,
 int ess,
 SingleClusterPolicy policy)

Constructs an instance of Ftfc.

Parameters:

dataSet - The dataset containing the variables and data from which the model will be built.

alpha - The significance level used for statistical testing.

ess - The equivalent sample size to be set.

policy - The single cluster policy defining the strategy for cluster formation and analysis.

Method Details

findClusters

public Map<List<Integer>,Integer> findClusters()

Runs the search and returns a graph of clusters with the ir respective latent parents.

Returns:

This a map from discovered clusters to their ranks.

setVerbose

public void setVerbose(boolean verbose)

Sets the verbose mode for the instance. When verbose is set to true, additional logging or detailed output may be enabled by the class.

Parameters:

verbose - A boolean flag indicating whether verbose mode should be enabled (true) or disabled (false).
