Description

This function gives the inverse of the F-distribution.
If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle FDIST(x,df_1,df_2)=prob} , then Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle NORMSINV(prob,df_1,df_2)=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 Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle df_1} and Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle df_2} 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.prob<0 or prob>1.

ZOS

The syntax is to calculate FINV in ZOS is Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle FINV (probability,DegreeOfFreedom1,DegreeOfFreedom2,accuracy)}
- Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle prob} is the associated value of F distribution.
