hypg_pdf

hypergeometric probability distribution

CALLING SEQUENCE

[pdf]=hypg_pdf(k,n,K,N)

PARAMETERS

Input

• k,n,K,N are the parameters as described above or matrix of parameters with the same size (pxq)

Output

• pdf = (pxq) vector containing pdf for each x

DESCRIPTION

Calculates the hypergeometric pdf 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)
