FINV(prob,df1,df2)


  • is the associated value of F distribution
  • and is the degrees of freedom.

Description

  • This function gives the inverse of the F-distribution.
  • If FDIST(x,df1,df2)=prob, then NORMSINV(prob,df1,df2)=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 df1 and df2 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.
  • 3. or ,and or

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
