F_INV

Returns the inverse of the (left-tailed) F probability distribution: if p = F.DIST(x,...), then F.INV(p,...) = x.

Syntax

expression.F_INV(arg1, arg2, arg3);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

NameRequired/OptionalData typeDefaultDescription
arg1RequiredApiRange | ApiName | numberA probability associated with the F cumulative distribution, a number between 0 and 1 inclusive.
arg2RequiredApiRange | ApiName | numberThe numerator degrees of freedom, a number between 1 and 10^10, excluding 10^10.
arg3RequiredApiRange | ApiName | numberThe denominator degrees of freedom, a number between 1 and 10^10, excluding 10^10.

Returns

number

Example

Return the inverse of the (left-tailed) F probability distribution.

// Calculate the inverse function where p = F.DIST(x,...) implies F.INV(p,...) = x.

// Determine critical F values using F_INV with probability and degrees of freedom.

let worksheet = Api.GetActiveSheet();
let func = Api.WorksheetFunction;
let ans = func.F_INV(0.01, 6, 4);
worksheet.GetRange("B2").SetValue(ans);
