In a compound Binomial distribution the skew(S) = B^3 * E (N-E(N)^3) according to the chapter on Risk Models.
How could I derive the E(N-E(N)^3) -> is it the third derivative of a moment generating funcion of binomial distribution evaluated at 0?
Is there any quicker and simpler way of deriving Skew (S) for compound binomial? It is not given in the tables as it is in case of compound Poisson.
