  1. lazy val aic: Double

    Akaike Information Criterion (AIC) for the fitted model.

    Akaike Information Criterion (AIC) for the fitted model.

  2. lazy val coefficientStandardErrors: Array[Double]

    Standard error of estimated coefficients and intercept.

    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.

  5. lazy val dispersion: Double

    The dispersion of the fitted model.

    The dispersion of the fitted model. It is taken as 1.0 for the "binomial" and "poisson" families, and otherwise estimated by the residual Pearson's Chi-Squared statistic (which is defined as sum of the squares of the Pearson residuals) divided by the residual degrees of freedom.
