PROBHYPR Function

Arguments

N

is an integer population size parameter, with N 1.

Range:

K

is an integer number of items in the category of interest parameter.

Range:

0 K N

n

is an integer sample size parameter.

Range:

0 n N

x

is an integer random variable.

Range:

max(0, K + n-N) x min(K,n)

r

is an optional numeric odds ratio parameter.

Range:

r 0

The PROBHYPR function returns the probability that an observation from an extended hypergeometric distribution, with population size N, number of items K, sample size n, and odds ratio r, is less than or equal to x. If the optional parameter r is not specified or is set to 1, the value returned is from the usual hypergeometric distribution.

x=probhypr(200,50,10,2);
