Public Function InverseFDistribution (probability As Double, firstDegreeOfFreedom As Integer, secondDegreeOfFreedom As Integer) As Double

Parameters

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

Double

A double value from the inverse F distribution function.

Exceptions

InvalidOperationException

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.
