FINV function

PRO

The FINV function in Jspreadsheet Formulas Pro returns the inverse of the F probability distribution: the value x whose cumulative probability equals the given probability. In Jspreadsheet it evaluates the left-tailed inverse and returns the same value as F.INV. This differs from Excel, where the compatibility function FINV returns the right-tailed inverse. Spreadsheets that rely on the Excel behavior should use F.INV.RT instead.

Documentation

Returns the inverse of the F probability distribution for a specified probability and degrees of freedom.

Category

Statistical

Syntax

FINV(probability, degrees_freedom1, degrees_freedom2)

Parameter Description
probability The cumulative probability, between 0 and 1.
degrees_freedom1 The numerator degrees of freedom. Must be at least 1.
degrees_freedom2 The denominator degrees of freedom. Must be at least 1.

Behavior

The FINV function returns the value x such that F.DIST(x, df1, df2, TRUE) equals probability. It is the left-tailed inverse.

  • FINV(0.05, 3, 5) returns 0.110945, the same as F.INV(0.05, 3, 5). Excel returns 5.409451 for the same call, which in Jspreadsheet is obtained with F.INV.RT(0.05, 3, 5) or F.INV(0.95, 3, 5).
  • probability 0 returns 0. Values above 1, and exactly 1, return #NUM!.
  • Both degrees of freedom must be at least 1. Otherwise the function returns #NUM!.
  • Text arguments return #VALUE!.

Common Errors

Error Description
#NUM! Returned when probability is negative or greater than or equal to 1, or when either degrees of freedom is less than 1.
#VALUE! Returned when an argument is text that cannot be interpreted as a number.

Best practices

  • Keep probability below 1. Exactly 1 and larger values return #NUM!.
  • Validate the input cells so that both degrees of freedom are at least 1.
  • Use absolute references for the degrees of freedom cells when copying the formula down a column of probability values, for example $B$1.
  • Check with ISNUMBER that the input cells hold numbers, because text returns #VALUE!.

Usage

A few examples using the FINV function.

FINV(0.05, 3, 5)
// Returns 0.110945, the left-tailed inverse (same as F.INV)

F.INV.RT(0.05, 3, 5)
// Returns 5.409451, the right-tailed inverse that Excel returns for FINV(0.05, 3, 5)

FINV(0.01, 10, 20)
// Returns 0.226994

FINV(1.5, 3, 5)
// Returns #NUM! because the probability is above 1
