Binomial function in python
WebWiki says that the compound distribution function is given by. f(k n,a,b) = comb(n,k) * B(k+a, n-k+b) / B(a,b) where B is the beta function, a and b are the original Beta parameters and n is the Binomial one. k here is your x and p disappears because you integrate over the values of p to obtain this (convolution). That is, you won't find it in ... WebNegative binomial distribution describes a sequence of i.i.d. Bernoulli trials, repeated until a predefined, non-random number of successes occurs. The probability mass function of the number of failures for nbinom is: f ( k) = ( k + n − 1 n − 1) p n ( 1 − p) k. for k ≥ 0, 0 < p ≤ 1. nbinom takes n and p as shape parameters where n is ...
