public interface PascalDistribution extends IntegerDistribution
The Pascal distribution. The Pascal distribution is a special case of the Negative Binomial distribution where the number of successes parameter is an integer. There are various ways to express the probability mass and distribution functions for the Pascal distribution. The convention employed by the library is to express these functions in terms of the number of failures in a Bernoulli experiment [2].
