CHIINV

Archived content. No warranty is made as to technical accuracy. Content may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

Returns the inverse of the one-tailed probability of the chi-squared distribution. If probability = CHIDIST(x,...), then CHIINV(probability,...) = x. Use this function to compare observed results with expected ones to decide whether your original hypothesis is valid.

Syntax

CHIINV ( probability , degrees_freedom )

Probability is a probability associated with the chi-squared distribution.

Degrees_freedom is the number of degrees of freedom.

Remarks

  • If either argument is nonnumeric, CHIINV returns the #VALUE! error value.

  • If probability < 0 or probability > 1, CHIINV returns the #NUM! error value.

  • If degrees_freedom is not an integer, it is truncated.

  • If degrees_freedom < 1 or degrees_freedom 10^10, CHIINV returns the #NUM! error value.

CHIINV uses an iterative technique for calculating the function. Given a probability value, CHIINV iterates until the result is accurate to within 3x10^-7. If CHIINV does not converge after 100 iterations, the function returns the #N/A error value.
