| − | The inverse cumulative density for the F-distribution with degrees of freedom dof1 and dof2. This returns the value x at which the area under the probability density graph falling to the left of x is p.

| − | The F-distribution is used in classical stastics for hypothesis testing involving the comparison of variances between two samples.
| |

| − | Note that there is no FDist distribution function built into Analytica. If you want an FDist, just use:
| |
| − | CumFDistInv(Uniform(0,1),dof1,dof2)
