Method Detail

coefficientStandardErrors

public double[] coefficientStandardErrors()

Standard error of estimated coefficients and intercept. This value is only available when the underlying WeightedLeastSquares using the "normal" solver.

If GeneralizedLinearRegression.fitIntercept is set to true, then the last element returned corresponds to the intercept.

Returns:

(undocumented)

numIterations

public int numIterations()

pValues

public double[] pValues()

Two-sided p-value of estimated coefficients and intercept. This value is only available when the underlying WeightedLeastSquares using the "normal" solver.

If GeneralizedLinearRegression.fitIntercept is set to true, then the last element returned corresponds to the intercept.

Returns:

(undocumented)

solver

public String solver()

tValues

public double[] tValues()

T-statistic of estimated coefficients and intercept. This value is only available when the underlying WeightedLeastSquares using the "normal" solver.

If GeneralizedLinearRegression.fitIntercept is set to true, then the last element returned corresponds to the intercept.

Returns:

(undocumented)

toString

public String toString()

Overrides:

toString in class Object
