WorksheetFunction.NormSInv Method
Excel Developer Reference |
Returns the inverse of the standard normal cumulative distribution. The distribution has a mean of zero and a standard deviation of one.
Syntax
expression.NormSInv(Arg1)
expression A variable that represents a WorksheetFunction object.
Parameters
Name | Required/Optional | Data Type | Description |
---|---|---|---|
Arg1 | Required | Double | Probability - a probability corresponding to the normal distribution. |
Return Value
Double
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.
