Julien, you mentioned commonly using nchoosek-like functions for k
outside the range [0 N]. Can you give an example?
Assume for a while that binocdf does not exist.
I meant "binopdf", of course.
Then, you could write a simple replacement as follows :
binopdf = @(k) (nchoosek (n, k) * (p ^ k) * (1 - p) ^ (n - k))
and it is valid for all non-negative k.
