FDIST arguments

| Argument | Description |
| --- | --- |
| value | The value at which you<br>want to evaluate the distribution. Value<br>must not be negative. |
| degrees\_freedom1 | A positive integer stating the number of numerator degrees of freedom. |
| degrees\_freedom2 | A positive<br>integer stating the number of denominator degrees of freedom. |

This function is related to the FInv function in the following way:   
`If prob = FDist(value, df1, df2), 
 then FInv(prob, df1, df2) = value`

Limitations:

All arguments must be numeric, else NULL will be returned.
