Graphs of the E-L {GW} simulated and theoretical PDF’s ( 200 fitted densities, density of mean of all fits, theoretical density) for sample sizes n = 50, 100, 200, 500 and 1000. The left column parameters: ξ = 0.5, μ =  − 1 and σ =  − 1. The middle column parameters: ξ = 2, μ = 0 and σ =  − 2. The right column parameters: ξ = 6, μ = 2 and σ =  − 3
