torch (version 0.11.0)

distr_poisson: Creates a Poisson distribution parameterized by rate, the rate parameter.

Description

Samples are nonnegative integers, with a pmf given by $${\text{rate}}^k\frac{e^{-\text{rate}}}{k!}$$

Usage

distr_poisson(rate, validate_args = NULL)

Arguments

rate

(numeric, torch_tensor): the rate parameter

validate_args

whether to validate arguments or not.
