Lognormal distribution

Use the lognormal distribution to model positive data values that are approximately symmetric or skewed to the right and greater than 0. The lognormal distribution is used for reliability analysis and in financial applications, such as modeling stock behavior.

The lognormal distribution is a continuous distribution that is defined by its location and scale parameters. The 3-parameter lognormal distribution is defined by its location, scale, and threshold parameters.

The shape of the lognormal distribution is similar to that of the loglogistic and Weibull distributions.
Lognormal distribution

This is the lognormal distribution for scale=1.0, location=0.0, and threshold=0.0.

The lognormal distribution is also known as the Cobb-Douglas distribution.
