val sample : ?rng:Gsl.Rng.t ->
       size:int ->
       t ->
       elt array

Samples size data points from the distribution.

val cumulative_probability : t ->
       n:elt -> float

Computes cumulative probability function for a given value n, i. e. P(X <= n), the probability that a random variable X will be found at a value less than or equal to n.

val probability : t ->
       n:elt -> float

Computes probability mass function for a given value n, i. e. P(X = n), the probability that a random variable X is exactly equal to n
