F.INV

F.INV(probability, degrees_freedom1, degrees_freedom2)

Returns the inverse of the probability distribution function for an f distribution (left tailed).

probability	The probability associated with the distribution.
degrees_freedom1	The numerator degrees of freedom.
degrees_freedom2	The denominator degrees of freedom.

REMARKS

* For an illustrated example refer to the page under Distributions
* The f distribution is a continuous distribution
* The random variable returned is often described as a critical value.
* If "probability" < 0, then #NUM! is returned.
* If "probability" > 1, then #NUM! is returned.
* If "probability" is not numeric, then #VALUE! is returned.
* If "degrees_freedom1" < 1, 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" is not an integer, it is truncated
* If "degrees_freedom2" is not numeric, then #VALUE! is returned.
* This function was added in Excel 2010 to replace the FINV function.
