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
The inverse of the lognormal distribution function is:
