hypg_cdf

hypergeometric cumulative distribution

CALLING SEQUENCE

[p]=hypg_cdf(k,n,K,N)

PARAMETERS

Input

* k,n,K,N= the parameters of the distibution (probability of k successes in n draws, without replacement, from a finite population of size N that contains exactly K successes, or matrix of parameters with the same size (pxq)

 

Output

* p = a (pxq) matrix of cumulative probabilities from the distribution

DESCRIPTION

Calculates the hypergeometric cdf function where the hypergeometric distribution corresponds to the probability of having k elements belonging to a class of size K in a random draw of n elements chosen among N.

EXAMPLE

p=hypg_pdf(5,15,20,30)
