# 3.5.3.3.8 InvF

## Definition:

The invf(value, m, n) function is the inverse F distribution function with m and n degrees of freedom. This function is used to calculate the p-value involving F distributions.

## Parameters:

value (input, double)
the value of F variate
m (input, integer)
the degrees of freedom of the numerator variance
n (input, integer)
the degrees of freedom of the denominator variance

## Example:

invf(3.682, 2, 15) = 0.94999
