Creates a Gamma distribution parameterized by shape concentration and rate.

Creates a Gamma distribution parameterized by shape concentration and rate.

Usage

distr_gamma(concentration, rate, validate_args = NULL)

Arguments

concentration

(float or Tensor): shape parameter of the distribution (often referred to as alpha)

rate

(float or Tensor): rate = 1 / scale of the distribution (often referred to as beta)

validate_args

whether to validate arguments or not.
