Returns the inverse of the standard normal cumulative distribution. The distribution has a mean of zero and a standard deviation of one.
Syntax
NORMSINV(probability)
Probability is a probability corresponding to the normal distribution.
Remarks
- If probability is nonnumeric, NORMSINV returns the #VALUE! error value.
- If probability < 0 or if probability > 1, NORMSINV returns the #NUM! error value.
Given a value for probability, NORMSINV seeks that value z such that NORMSDIST(z) = probability. Thus, precision of NORMSINV depends on precision of NORMSDIST. NORMSINV uses an iterative search technique. If the search has not converged after 100 iterations, the function returns the #N/A error value.
