mhygepdf

Multivariate hypergeometric probability density function.

This m-file returns the multivariate hypergeometric probability density function at M with integer parameters in N. Note: The density function is zero unless the elements in M are integers.

If there are m_i elements of class i in a population and you take n elements at random without replacement, then the number of elements ofeach class in the sample (x_1,x_2,...,x_c) has the multivariate hypergeometric distribution. This has the same relationship to the multinomial distribution that the hypergeometric distribution has to the binomial distribution--the multinomial distribution is the 'with-replacement' distribution and the multivariate hypergeometric is the 'without-replacement' distribution.

Syntax: function x = mhygepdf(m,n)

Inputs:
m - vector of total (population) elements of class i
n - vector of sampled elements of class i

Output:
x - multivariate hypergeometric probability for values x_1,x_2,...,x_c
