StatsFCDF

StatsFCDF (x, n1, n2)​

The StatsFCDF function returns the cumulative distribution function for the F distribution with shape parameters n1 and n2

F(x;n1,n2)=1−Betai(n22,n12,n2n2+n1x),\displaystyle F\left(x ; n_{1}, n_{2}\right)=1-{Betai}\left(\frac{n_{2}}{2}, \frac{n_{1}}{2}, \frac{n_{2}}{n_{2}+n_{1} x}\right),

where Betai is the incomplete beta function.
