  1. lazy val aic: Double

    Akaike Information Criterion (AIC) for the fitted model.

    Akaike Information Criterion (AIC) for the fitted model.

  2. lazy val degreesOfFreedom: Long

    Degrees of freedom.

    Degrees of freedom.

    Annotations
    @Since("2.0.0")
  3. lazy val deviance: Double

    The deviance for the fitted model.

    The deviance for the fitted model.

    Annotations
    @Since("2.0.0")
  4. 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.

  7. val predictionCol: String

    Field in "predictions" which gives the predicted value of each instance.
