FINV (probability,DegreeOfFreedom1,DegreeOfFreedom2,Accuracy,DivisionMinMaxArray)

$probability$ is the associated value of F distribution
$DegreeOfFreedom1$ and $DegreeOfFreedom2$ is the degrees of freedom.

Description

This function gives the inverse of the F-distribution.
If $FDIST(Number,DegreeOfFreedom1,DegreeOfFreedom2)=probability$ , then $NORMSINV(Probability)=x$ .FINV using the iterating method to find the value of x.
Suppose the iteration has not converged after 100 searches, then the function gives the error result.
FINV can be used to return critical values from the F distribution
The calculation of analysis of variance includes the data for F probability for the significance level 0.05.
When the value of $DegreeOfFreedom1$ and $DegreeOfFreedom2$ are not integers ,then it is converted in to integers.
This function will return the result as error when
1. any one of the argument is nonnumeric.
2.probability<0 or probability>1.
3. $DegreeOfFreedom1$ or $DegreeOfFreedom2<1$ ,and $DegreeOfFreedom1$ or $DegreeOfFreedom2>=10^{10}$

ZOS

The syntax is to calculate FINV in ZOS is
- $probability$ is the associated value of F distribution.
For e.g., FINV(0.293,4,5)

Examples

FINV(0.01526530981,7,3) = 20.658810208868587
FINV(0.001,5,1) = 199.9
FINV(0,4,2) = 199.9
FINV(-1,7,2) = #ERROR
