FDIST

FDIST(x, degrees_freedom1, degrees_freedom2)

Returns the probability distribution function for an f distribution (left tailed) (no cumulative).

x	The number from the distribution.
degrees_freedom1	The numerator degrees of freedom.
degrees_freedom2	The denominator degrees of freedom.

REMARKS

* F.DIST was added in Excel 2010 to replace this function and include an option for cumulative probability.
* F.DIST.RT was added in Excel 2010 to replace this function.
* The f distribution is a [[continuous distribution]].
* The f distribution is not symmetrical.
* If "x" < 0, then #NUM! is returned.
* If "x" is not numeric, then #VALUE! is returned.
* If "degrees_freedom1" < 1, then #NUM! is returned.
* If "degrees_freedom1" = 10^10, then #NUM! is returned.
* If "degrees_freedom1" is not an integer, it is truncated.
* If "degrees_freedom1" is not numeric, then #VALUE! is returned.
* If "degrees_freedom2" < 1, then #NUM! is returned.
* If "degrees_freedom2" = 10^10, then #NUM! is returned.
* If "degrees_freedom2" is not an integer, it is truncated.
* If "degrees_freedom2" is not numeric, then #VALUE! is returned.
* All the values are greater than zero.
