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

Compute mean and variance of the F distribution.

Arguments

  • m is the first parameter of the F distribution. The elements of m must be positive
  • n is the second parameter of the F distribution. The elements of n must be positive

m and n must be of common size or one of them must be scalar

Return values

  • mn is the mean of the F distribution. The mean is undefined for n not greater than 2
  • v is the variance of the F distribution. The variance is undefined for n not greater than 4

Examples

m = 1:6;
n = 5:10;
[mn, v] = fstat (m, n)



[mn, v] = fstat (m, 5)
