hygestat (Statistics Toolbox)

Mean and variance for the hypergeometric distribution.

Syntax

[MN,V] = hygestat(M,K,N)

Description

For the hypergeometric distribution:

The mean is .
The variance is .

Examples

The hypergeometric distribution approaches the binomial where
p = K/M as M goes to infinity.

[m,v] = hygestat(10.^(1:4),10.^(0:3),9)

m =

    0.9000    0.9000    0.9000    0.9000

v =

    0.0900    0.7445    0.8035    0.8094

[m,v] = binostat(9,0.1)

m =

    0.9000

v =

    0.8100
