| |
| − | The inverse cumulative density for the F-distribution with degrees of freedom «dof1» and «dof2». This returns the value <code>x</code> at which the area under the probability density graph falling to the left of <code>x</code> is «p».
| |
| − | | |
| − | 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:
| |
| − | :<code>CumFDistInv(Uniform(0, 1), dof1, dof2)</code>
| |
| − | | |
| − | [[CumFDistInv]] and [[CumFDist]] are inverses, i.e., within the range of the distribution:
| |
| − | :<code>CumFDistInv(CumFDist(x, dof1, dof2), dof1, dof2) → x</code>
