Abstract

The Pareto distribution is a heavy-tailed distribution with many applications in the realworld. The tail of the distribution is important, but the threshold of the distribution is difficultto determine in some situations. In this paper we consider two real-world examples with heavy-tailed observations, which leads us to propose a mixture truncated Pareto distribution MTPDand study its properties. We construct a cluster truncated Pareto distribution CTPD by usinga two-point slope technique to estimate the MTPD from a random sample. We apply the MTPDand CTPD to the two examples and compare the proposed method with existing estimationmethods. The results of log-log plots and goodness-of-fit tests show that the MTPD and thecluster estimation method produce very good fitting distributions with real-world data.
