FINV(prob,df1,df2)
- is the associated value of F distribution
- and is the degrees of freedom.
is the associated value of F distribution
and 
is the degrees of freedom.Description
- This function gives the inverse of the F-distribution.
- If , then .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.

, then 
.FINV using the iterating method to find the value of x.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.
- 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
