LOGINV

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).

The inverse of the lognormal distribution function is:

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.

Example

LOGINV(0.039084, 3.5, 1.2) equals 4.000014
