A random variable follows this distribution if the logarithm of the random variable is normally distributed. Use when random variables are greater than 0. Used for reliability analysis and in financial applications, such as modeling stock behavior. The lognormal distribution is also known as the Cobb-Douglas distribution.
The lognormal distribution is defined by 3 parameters: location, scale, and threshold.
|
This is the lognormal distribution for scale = 1.0, location = 0, and threshold = 0.0. |
The shape of the lognormal distribution is similar to that of the loglogistic and Weibull distributions.
