- probability
- Double
The alpha value, which is the probability that the hypothesis is rejected. The allowable range is 0-1.
- firstDegreeOfFreedom
- Int32
First degree of freedom.
- secondDegreeOfFreedom
- Int32
Second degree of freedom.
Returns
A double value from the inverse F distribution function.
Exceptions
Condition: Cannot continue calculation using specified parameter values because of limitation.
Remarks
This method returns the F value for the given F distribution probability.
The F distribution can be used in an F-test that compares the degree of variability in two data sets.
This method may return an exception depending on the parameter values.
