Compatibility - NORMINV Function
The NORMINV function replaces the NORM.INV function in Excel 2010.
Description
The function returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.
Syntax
NORMINV (probability,mean,standard_dev)
Arguments
Argument | Description | Required/ Optional |
---|---|---|
Probability | A probability corresponding to the normal distribution. | Required |
Mean | The arithmetic mean of the distribution. | Required |
Standard_dev | The standard deviation of the distribution. | Required |
Notes
If any argument is nonnumeric, NORMINV returns the #VALUE! error value.
If probability <= 0 or if probability >= 1, NORMINV returns the #NUM! error value.
If standard_dev ≤ 0, NORMINV returns the #NUM! error value.
If mean = 0 and standard_dev = 1, NORMINV uses the standard normal distribution (see NORMSINV).
Given a value for probability, NORMINV seeks that value x such that NORMDIST(x, mean, standard_dev, TRUE) = probability. Hence, precision of NORMINV depends on precision of NORMDIST. NORMINV uses an iterative search technique. If the search has not converged after 100 iterations, the function returns the #N/A error value.
