Function File: [mn, v] = hygestat (t, m, n)

Compute mean and variance of the hypergeometric distribution.

Arguments

• t is the total size of the population of the hypergeometric distribution. The elements of t must be positive natural numbers
• m is the number of marked items of the hypergeometric distribution. The elements of m must be natural numbers
• n is the size of the drawn sample of the hypergeometric distribution. The elements of n must be positive natural numbers

t, m, and n must be of common size or scalar

Return values

• mn is the mean of the hypergeometric distribution
• v is the variance of the hypergeometric distribution

Examples

          t = 4:9;
          m = 0:5;
          n = 1:6;
          [mn, v] = hygestat (t, m, n)
          
          [mn, v] = hygestat (t, m, 2)
