Statistical - CHISQ.INV.RT Function
Description
The CHISQ.INV.RT function returns the inverse of the right-tailed probability of the chisquared distribution. If probability = CHISQ.DIST.RT(x...), then CHISQ.INV.RT(probability,...) = x.
Use this function to compare observed results with expected ones in order to decide whether your original hypothesis is valid.
Syntax
CHISQ.INV.RT (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, CHISQ.INV.RT returns the #VALUE! error value
If probability < 0 or probability > 1, CHISQ.INV.RT returns the #NUM! error value
If deg_freedom < 1, CHISQ.INV.RT returns the #NUM! error value
Given a value for probability, CHISQ.INV.RT seeks that value x such that CHISQ.DIST.RT(x, deg_freedom) = probability. Thus, precision of CHISQ.INV.RT depends on precision of CHISQ.DIST.RT.
CHISQ.INV.RT uses an iterative search technique. If the search has not converged after 64 iterations, the function returns the #N/A error value.
Applicability
Excel 2010, Excel 2013, Excel 2016
