NORMSINV

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

NORMSINV uses an iterative technique for calculating the function. Given a probability value, NORMSINV iterates until the result is accurate to within ± 3x10^-7. If NORMSINV does not converge after 100 iterations, the function returns the #N/A error value.

Example

Formula Description (Result)
=NORMSINV(0.908789) Inverse of the standard normal cumulative distribution, with a probability of 0.908789 (1.3333)
