Glossary Definition

Last Updated: 2007-11-07


This is the probability distribution of any random variable whose logarithm is normally distributed. Thus, if Y is a random variable with a normal distribution, then exp(Y) has a log normal distribution. This distribution can be used to model nonzero positively skewed data.
