CHISQ_DIST

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

Syntax

expression.CHISQ_DIST(arg1, arg2, arg3);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

Name	Required/Optional	Data type	Default	Description
arg1	Required	ApiRange | ApiName | number		The value at which the distribution will be evaluated, a nonnegative number.
arg2	Required	ApiRange | ApiName | number		The number of degrees of freedom, a number between 1 and 10^10, excluding 10^10.
arg3	Required	ApiRange | ApiName | boolean		A logical value that determines the form of the function. If this argument is equal to true, the cumulative distribution function is returned; if it is equal to false, the probability density function is returned.

Returns

number

Example

Get the cumulative percentage of results up to a specific point in a chi-squared distribution in a spreadsheet.

// Determine what portion of the distribution falls at or below a given value in a spreadsheet.

// Evaluate how likely it is to see results less than or equal to an observed chi-squared value in a spreadsheet.

let worksheet = Api.GetActiveSheet();
let func = Api.WorksheetFunction;
worksheet.GetRange("A1").SetValue(func.CHISQ_DIST(2, 3, false));
