distr_gamma function

Creates a Gamma distribution parameterized by shape concentration and rate.

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.

Examples

if (torch_is_installed()) {
m <- distr_gamma(torch_tensor(1.0), torch_tensor(1.0))
m$sample() # Gamma distributed with concentration=1 and rate=1
}
