sample

open override fun sample(random: Random): Int(source)

Draws a single random integer from this Poisson distribution.

For small rates (lambda < 30), uses Knuth's algorithm which multiplies uniform random numbers until their product falls below exp(-lambda). For large rates, uses a normal approximation with the result clamped to non-negative values.

Return

a random non-negative integer drawn from this distribution.

Parameters

random

the source of randomness.
