Different texts (and even different parts of this article) adopt slightly different definitions for the negative binomial distribution. They can be distinguished by whether the support starts at k = 0 or at k = r, whether p denotes the probability of a success or of a failure, and whether r represents success or failure, [1] so identifying the specific parametrization used is crucial in any ...
In probability theory, a beta negative binomial distribution is the probability distribution of a discrete random variable ... Note, at the end of the experiment, ...
Let p = α/(α + β) and suppose α + β is large, then X approximately has a binomial(n, p) distribution. If X is a binomial (n, p) random variable and if n is large and np is small then X approximately has a Poisson(np) distribution. If X is a negative binomial random variable with r large, P near 1, and r(1 − P) = λ, then X approximately ...
Note that the Panjer distribution reduces to the Poisson distribution in the limit case ; it coincides with the negative binomial distribution for positive, finite real numbers >, and it equals the binomial distribution for negative integers .
The multinomial distribution, a generalization of the binomial distribution. The multivariate normal distribution, a generalization of the normal distribution. The multivariate t-distribution, a generalization of the Student's t-distribution. The negative multinomial distribution, a generalization of the negative binomial distribution.
Binomial distribution, for the number of "positive occurrences" (e.g. successes, yes votes, etc.) given a fixed total number of independent occurrences; Negative binomial distribution, for binomial-type observations but where the quantity of interest is the number of failures before a given number of successes occurs

It is a truncated version of the negative binomial distribution [1] for which estimation methods have been studied. [2] In the context of actuarial science, the distribution appeared in its general form in a paper by K. Hess, A. Liewald and K.D. Schmidt [3] when they characterized all distributions for which the extended Panjer recursion works.
