Constructor Details

GeneralizedSemEstimator

public GeneralizedSemEstimator()

Constructs a new GeneralizedSemEstimator.

Method Details

estimate

public GeneralizedSemIm estimate(GeneralizedSemPm pm,
 DataSet data)

Maximizes likelihood equation by equation. Assumes the equations are recursive and that each has exactly one error term.

Parameters:

pm - a GeneralizedSemPm object

data - a DataSet object

Returns:

a GeneralizedSemIm object

getReport

public String getReport()

Retrieves the report generated by the GeneralizedSemEstimator.

Returns:

The report as a String.

getaSquaredStar

public double getaSquaredStar()

Returns the value of the field aSquaredStar.

Returns:

the value of aSquaredStar
