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.
