WorksheetFunction.LogNormDist Method
Returns the cumulative lognormal distribution of x, where ln(x) is normally distributed with parameters mean and standard_dev. Use this function to analyze data that has been logarithmically transformed.
Syntax
expression.LogNormDist(Arg1, Arg2, Arg3)
expression A variable that represents a WorksheetFunction object.
Parameters
| Name | Required/Optional | Data Type | Description |
|---|---|---|---|
| Arg1 | Required | Double | X - the value at which to evaluate the function. |
| Arg2 | Required | Double | Mean - the mean of ln(x). |
| Arg3 | Required | Double | Standard_dev - the standard deviation of ln(x). |
Return Value
Double
Remarks
- If any argument is nonnumeric, LOGNORMDIST returns the #VALUE! error value.
- If x ≤ 0 or if standard_dev ≤ 0, LOGNORMDIST returns the #NUM! error value.
- The equation for the lognormal cumulative distribution function is:
