114.  final val variancePower: DoubleParam

     Param for the power in the variance function of the Tweedie distribution which provides the relationship between the variance and mean of the distribution.

     Param for the power in the variance function of the Tweedie distribution which provides the relationship between the variance and mean of the distribution. Only applicable to the Tweedie family. (see Tweedie Distribution (Wikipedia)) Supported values: 0 and [1, Inf). Note that variance power 0, 1, or 2 corresponds to the Gaussian, Poisson or Gamma family, respectively.
