The Negative Binomial distribution is a discrete distribution
bounded
on the low side at 0 and unbounded on the high side. The Negative
Binomial distribution gives the number of failures before the nth success in a sequence of independent
Bernoulli trials with probability p of
success on each trial.
The Negative Binomial distribution has many uses; some occur because it
provides a good approximation for the sum or mixing of other discrete
distributions. By itself, it is used to model accident statistics,
birth-and-death processes, market research and consumer expenditure,
lending library data, biometrical data, and many others.
