CHISQ.INV - Daxplained

CHISQ.INV is a DAX function that returns the inverse of the left-tailed probability of the chi-squared distribution.

Syntax

CHISQ.INV(
   Probability,
   Deg_freedom
)

Argument	Properties	Description
Probability		A probability associated with the chi-squared distribution.
Deg_freedom		The number of degrees of freedom.

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

If argument is nonnumeric, CHISQ.INV returns the #VALUE! error value.
If probability < 0 or probability > 1, CHISQ.INV returns the #NUM! error value.
If deg_freedom is not an integer, it is rounded.
If deg_freedom < 0 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Formula	Description	Result
`= CHISQ.INV(0.93,1)`	Inverse of the left-tailed probability of the chi-squared distribution for 0.93, using 1 degree of freedom.	5.318520074
`= CHISQ.INV(0.6,2)`	Inverse of the left-tailed probability of the chi-squared distribution for 0.6, using 2 degrees of freedom.	1.832581464
