In this paper we present the tools used in the modeling of distributions with fat tails in the theory of extreme values. We present three tools: the sample distribution function, the histograms for grouped data and the kernel densities. The latter is described in detail. The presented examples show the application of the kernel densities to modeling the generalized Pareto distributions.
