CHISQ.INV.RT

  • Article

Applies to: Calculated column Calculated table Measure Visual calculation

Returns the inverse of the right-tailed probability of the chi-squared 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)

Parameters

Term Definition
Probability A probability associated with the chi-squared distribution.
Deg_freedom The number of degrees of freedom.

Return value

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

Remarks

  • 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 is not an integer, it is rounded.

  • 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.

  • This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
