Method Details

randomSingleFactorModel

public static Graph randomSingleFactorModel(int numStructuralNodes,
 int numStructuralEdges,
 int numMeasurementsPerLatent,
 int numLatentMeasuredImpureParents,
 int numMeasuredMeasuredImpureParents,
 int numMeasuredMeasuredImpureAssociations)

randomSingleFactorModel.

Parameters:

numStructuralNodes - a int

numStructuralEdges - a int

numMeasurementsPerLatent - a int

numLatentMeasuredImpureParents - a int

numMeasuredMeasuredImpureParents - a int

numMeasuredMeasuredImpureAssociations - a int

Returns:

a Graph object

randomMim

public static Graph randomMim(Graph graph,
 int numMeasurementsPerLatent,
 int numLatentMeasuredImpureParents,
 int numMeasuredMeasuredImpureParents,
 int numMeasuredMeasuredImpureAssociations,
 boolean arrangeGraph)

randomMim.

Parameters:

graph - a Graph object

numMeasurementsPerLatent - a int

numLatentMeasuredImpureParents - a int

numMeasuredMeasuredImpureParents - a int

numMeasuredMeasuredImpureAssociations - a int

arrangeGraph - a boolean

Returns:

a Graph object

randomBifactorModel

public static Graph randomBifactorModel(int numStructuralNodes,
 int numStructuralEdges,
 int numMeasurementsPerLatent,
 int numLatentMeasuredImpureParents,
 int numMeasuredMeasuredImpureParents,
 int numMeasuredMeasuredImpureAssociations)

First a random single factor model is created with the specified number of latent nodes and latent edges, and impurity structure. Then this is converted to a bifactor model by adding new latents and edges.

Parameters:

numStructuralNodes - a int

numStructuralEdges - a int

numMeasurementsPerLatent - a int

numLatentMeasuredImpureParents - a int

numMeasuredMeasuredImpureParents - a int

numMeasuredMeasuredImpureAssociations - a int

Returns:

a Graph object
