CHISQ_INV_RT
Returns the inverse of the right-tailed probability of the chi-squared distribution.
Syntax
expression.CHISQ_INV_RT(arg1, arg2);
expression - A variable that represents a ApiWorksheetFunction class.
Parameters
| Name | Required/Optional | Data type | Default | Description |
|---|---|---|---|---|
| arg1 | Required | ApiRange | ApiName | number | A probability associated with the chi-squared distribution, a value between 0 and 1 inclusive. | |
| arg2 | Required | ApiRange | ApiName | number | The number of degrees of freedom, a number between 1 and 10^10, excluding 10^10. |
Returns
number
Example
Convert an upper-tail probability into the matching chi-squared critical value in a spreadsheet.
// Determine the boundary value for statistical significance at a given right-tail probability in a spreadsheet.
// Find the threshold point used to evaluate extreme results in hypothesis testing in a spreadsheet.
