BetaBinomialDistribution

BetaBinomialDistribution[, , n]
represents a beta binomial mixture distribution with beta distribution parameters and , and binomial trials.

Details Details

BetaBinomialDistribution is also known as a Polya distribution and as a negative hypergeometric distribution.
The beta binomial distribution is a binomial distribution with n trials whose probability parameter follows a beta distribution with shape parameters and . »
BetaBinomialDistribution allows and to be any positive real numbers, and n to be any positive integer.
BetaBinomialDistribution can be used with such functions as Mean, CDF, and RandomVariate. »
