F(M, N, X)
This function returns the integral of Snedecor's F-distribution with M and N degrees of freedom from minus infinity to X.
Parameters
M, N
degrees of freedom
X
upper bound
Examples
F(14, 35, 99) = 1
F(D3, W2, Y8) = Error - F, degrees of freedom must be 0
where D3 = .5, W2 = 0, and Y8 = .99
F(B1, B2, B3) = 0.77459667
where B1 = 1, B2 = 2, and B3 = 3
