CHIINV |
CHIINV(probability, degrees_freedom) |
Returns the inverse of the probability distribution function for a chi-squared distribution (right tailed). |
probability | The probability associated with the distribution. |
degrees_freedom | The number of degrees of freedom. |
REMARKS |
* This function is only available for backwards compatibility and should not be used. * CHISQ.INV.RT was added in Excel 2010 to replace this function. * The chi-squared distribution is a [[continuous distribution]] * If "probability" < 0, then #NUM! is returned. * If "probability" > 1, then #NUM! is returned. * If "probability" is not numeric, then #VALUE! is returned. * If "degrees_freedom" is not an integer, it is truncated. * If "degrees_freedom" < 1, then #NUM! is returned. * If "degrees_freedom" = 10^10, then #NUM! is returned. * If "degrees_freedom" is not numeric, then #VALUE! is returned. * This function iterates until the result is accurate to within ±3x10^-7. * If the iterative process does not converge after 100 iterations, then #N/A is returned. * You can use the CHISQ.DIST function to return the probability distribution function OR the cumulative probability function for a chi-squared distribution (left tailed). * You can use the CHISQ.DIST.RT function to return the probability distribution function for a chi-squared distribution (right tailed) (no cumulative). * You can use the CHISQ.INV function to return the inverse of the probability distribution function for a chi-squared distribution (left tailed). * You can use the CHISQ.TEST function to return the probability value from a chi-squared distribution. * For the Microsoft documentation refer to support.microsoft.com * For the Google documentation refer to support.google.com |
