FINV(probability, degrees_freedom1, degrees_freedom2)

Returns the probability of getting greater than a particular value in an f distribution (left tailed).

probabilityThe probability associated with this distribution.
degrees_freedom1The numerator degrees of freedom.
degrees_freedom2The denominator degrees of freedom.

Remarks

* F.INV.RT was added in Excel 2010 to replace this function.
* The f distribution is a continuous distribution.
* The random variable returned by this function is often referred to 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" = 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.
* If this function does not converge after 100 iterations, then #N/A is returned.
* In Excel 2010 the accuracy of this function was improved.
