Returns the inverse of the lognormal cumulative distribution function of x, where ln(x) is normally distributed with parameters mean and standard_dev. If p = LOGNORMDIST(x,...) then LOGINV(p,...) = x.
Use the lognormal distribution to analyze logarithmically transformed data.
Syntax
LOGINV(probability,mean,standard_dev)
Probability is a probability associated with the lognormal distribution.
Mean is the mean of ln(x).
Standard_dev is the standard deviation of ln(x).
Remarks
- If any argument is nonnumeric, LOGINV returns the #VALUE! error value.
- If probability < 0 or probability > 1, LOGINV returns the #NUM! error value.
- If standard_dev <= 0, LOGINV returns the #NUM! error value.
-
The inverse of the lognormal distribution function is:
