WebMay 2, 2005 · We fitted a lognormal model by calculating moments under a log transformation. The bulk of the distribution clearly fits the lognormal model better, but the tail is closer to the Pareto model. By conventional goodness-of-fit measures, the Pareto model is a better fit.

"WebIt applies when you model the scale (location for the log scale); for the lognormal, the μ parameter acts as the log of a scale parameter, while for the gamma, the scale is the parameter that isn't the shape parameter (or its reciprocal if you use the shape-rate parameterization). I'll call the scale parameter for the gamma distribution β. " - Pareto vs lognormal
