Proposed Disposition of DIS 29500 Comment CO-0197 (Modified: 2008-01-13) Agreed; the following changes will be made to Part4, ยง3.17.7.227, page 2,724, line 18, and page 2,725, line 7: Description: Computes the inverse of the normal distribution for the specified mean and standard deviation. NORMINV uses an iterative search technique. … However, if probability < 0 or if probability > 1, #NUM! is returned. standard-deviation 0, #NUM! is returned. an implementation uses an iterative search technique, and T t he search has not converged after an implementation-defined number of iterations, #N/A is returned.
