Notes

The beta-binomial distribution is a binomial distribution with a probability of success p that follows a beta distribution.

The probability mass function for betabinom is:

f (k) = (k n) \frac{B ( k + a , n - k + b )}{B ( a , b )}

for $k \in {0, 1, \dots, n}$ , $n \geq 0$ , $a > 0$ , $b > 0$ , where $B (a, b)$ is the beta function.

betabinom takes $n$ , $a$ , and $b$ as shape parameters.
