bernoulli :: Distribution (Bernoulli b) a => b -> RVar a Source

Generate a Bernoulli variate with the given probability. For Bool results, bernoulli p will return True (p*100)% of the time and False otherwise. For numerical types, True is replaced by 1 and False by 0.

boolBernoulli :: (Fractional a, Ord a, Distribution StdUniform a) => a -> RVar Bool Source

A random variable whose value is True the given fraction of the time and False the rest.

generalBernoulli :: Distribution (Bernoulli b) Bool => a -> a -> b -> RVar a Source

generalBernoulli t f p generates a random variable whose value is t with probability p and f with probability 1-p.
