class Statistics::Distributions::Bernoulli

Overview

The discrete probability distribution of a random variable which takes the value 1 with probability p and the value 0 with probability q=1-p (source: wikipedia).

Defined in:

lib/distributions.cr

Constructors

.new(p : Float64)
Creates Bernoulli distribution with success rate p.

Instance Method Summary

#pmf(x)
