[M,V] = fstat(V1,V2)
[M,V] = fstat(V1,V2) returns
the mean of and variance for the F distribution

The mean of the F distribution for values of ν2 greater than 2 is
The variance of the F distribution for values of ν2 greater than 4 is
The mean of the F distribution is undefined if ν2 is less than 3. The variance is undefined for ν2 less than 5.
