Determining Parameters of Lognormal Distributions from Minimal Information

Abstract

The lognormal distribution has a number of properties that do not lend themselves to simple "back-of-the-envelope" calculations. Mathematical relationships are presented for the basic parameters of the lognormal distribution as a function of characteristics available to, or needed by, the risk analyst. A freeware computer program called LOGNORM4 has been written to take the tedium out of determining various characteristics of lognormal distributions, given one of fifteen sets of values that uniquely specify a lognormal distribution.
