Hi all,

I know that a given coin with a certain bias p was flipped an unknown number of times N, and came up heads z times. Both z and p are known, and I want to draw random samples of N from this distribution. The pdf of this distribution is

negativebinopdf = @(z,N,theta) (z/N)*(nchoosek(N,z))*(theta.^z).*((1-theta).^(N-z));

I don't know how I can draw random numbers of N for this distribution. Anyone has a clue?

Thanks!
