Diagnostic plots

This page illustrates diagnostic plots provided by the ExtremePlots.jl package. These plots help assess the fit of extreme value models and explore the distribution of extreme data.

Setup

Load the required packages:

using Distributions, ExtremePlots, Gadfly

Simulate data from a Generalized Extreme Value (GEV) distribution:

pd = GeneralizedExtremeValue(0,1,0)
y = rand(pd, 300);

Histogram Plot

Displays a histogram of the data with the distribution overlay.
