CHISQ_INV

Returns the inverse of the left-tailed probability of the chi-squared distribution.

Syntax

expression.CHISQ_INV(arg1, arg2-);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

NameRequired/OptionalData typeDefaultDescription
arg1RequiredApiRange | ApiName | numberA probability associated with the chi-squared distribution, a value between 0 and 1 inclusive.
arg2-RequiredApiRange | ApiName | numberThe number of degrees of freedom, a number between 1 and 10^10, excluding 10^10.

Returns

number

Example

Convert a left-tail probability into the matching chi-squared critical value in a spreadsheet.

// Identify the boundary point where cumulative results reach a specified probability level in a spreadsheet.

// Establish the threshold value for statistical tests based on a given tail probability in a spreadsheet.

let worksheet = Api.GetActiveSheet();
let func = Api.WorksheetFunction;
let ans = func.CHISQ_INV(0.4, 10);
worksheet.GetRange("B2").SetValue(ans);
