| nu2

| Return Type
| nonnegative |
| Synopsis
| This function returns a random F distributed
or Variance-ratio distributed number with average nu1/(nu2-2).
If X1 and X2 are Chi-square distributed variables with
parameters nu1 and nu2, then X1/X2 is distributed as FDist(nu1,nu2).
This distribution has a non-finite expected value for nu2<=2 and
non-finite variance for nu2<=4.
FDist_Rand uses Rand() which can be seeded by either the
function SetRand or SetRandSeed. |
