Method Detail

numIterations

public int numIterations()

solver

public String solver()

coefficientStandardErrors

public double[] coefficientStandardErrors()

Standard error of estimated coefficients and intercept.

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

Returns:

tValues

public double[] tValues()

T-statistic of estimated coefficients and intercept.

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

Returns:

(undocumented)

pValues

public double[] pValues()

Two-sided p-value of estimated coefficients and intercept.
