Compatibility - CHIINV Function
The CHIINV function replaces the CHISQ.INV.RT function in Excel 2010.
Description
The function returns the inverse of the right-tailed probability of the chi-squared distribution.
If probability = CHIDIST(x...), then CHIINV (probability...) = x
Syntax
CHIINV (probability,deg_freedom)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Probability | A probability associated with the chi-squared distribution. | Required |
| Deg_freedom | The number of degrees of freedom. | Required |
Notes
If deg_freedom is not an integer, it is truncated.
If either argument is nonnumeric, CHIINV returns the #VALUE! error value.
If probability < 0 or probability > 1, CHIINV returns the #NUM! error value.
If deg_freedom < 1, CHIINV returns the #NUM! error value.
Given a value for probability, CHIINV seeks value x such that CHIDIST(x, deg_freedom) = probability. Hence, precision of CHIINV depends on precision of CHIDIST. CHIINV uses an iterative search technique. If the search has not converged after 100 iterations, the function returns the #N/A error value.
