CumFDist

CumFDist(x, dof1, dof2)

The cumulative density at «x» for the F-distribution with degrees of freedom «dof1» and «dof2». This is the area under the probability density graph falling to the left of «x».

The F-distribution is used in classical statistics 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)
