LOGNORM.INV function: Description, Usage, Syntax, Examples and Explanation
What is LOGNORM.INV function in Excel?
Syntax of LOGNORM.INV function
LOGNORM.INV(probability, mean, standard_dev)
The LOGNORM.INV function syntax has the following arguments:
- Probability Required. A probability associated with the lognormal distribution.
- Mean Required. The mean of ln(x).
- Standard_dev Required. The standard deviation of ln(x).
LOGNORM.INV formula explanation
- If any argument is nonnumeric, LOGNORM.INV returns the #VALUE! error value.
- If probability <= 0 or probability >= 1, LOGNORM.INV returns the #NUM! error value.
- If standard_dev <= 0, LOGNORM.INV returns the #NUM! error value.
