Negative binomial distribution

Negative binomial distribution and exponential families
We show here that the family of negative binomial distributions NBk(n, p) for a given value of k form a 1-parameter exponential family. As a consequence : ...

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 ...
