StatisticFormula.InverseFDistribution(Double, Int32, Int32) Method

Definition

Returns the inverse of the F cumulative distribution.

public:
 double InverseFDistribution(double probability, int firstDegreeOfFreedom, int secondDegreeOfFreedom);
public double InverseFDistribution (double probability, int firstDegreeOfFreedom, int secondDegreeOfFreedom);
member this.InverseFDistribution : double * int * int -> double
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

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.
