FINV
Syntax:
FINV ( probability , degrees-freedom-1 , degrees-freedom-2 )
Description: Computes the inverse of the F probability distribution. Given a value for probability, FINV seeks that value x such that FDIST(x, degrees-freedom1, degrees-freedom2) = probability. Thus, precision of FINV depends on precision of FDIST. FINV uses an iterative search technique.

The number of degrees of freedom for the denominator, truncated to an integer. |
Return Type and Value: number – The inverse of the F probability distribution.
However, if
probability < 0 or probability > 1,
#NUM!is returned.degrees-freedom-1 < 1 or degrees-freedom-1 ≥ 1010,
