The binomial distribution function also has a nice relationship to the beta distribution function. The distribution function Fn can be written in the form Fn(k) = n! (n − k − 1)!k!∫1 − p 0 xn − k − 1(1 − x)kdx, k ∈ {0, 1, …, n} Proof

Webtl;dr you're going to get a likelihood of zero (and thus a negative-infinite log-likelihood) if the response variable is greater than the binomial N (which is the theoretical maximum value of the response). In most practical problems, N is taken as known and just the probability is estimated. If you do want to estimate N, you need to (1) constrain it to be >= the largest …
