Abstract

Right-tailed distributions are very important in many applications. There are many studies estimating the tail index. In this paper, we will estimate the tail parameter (⍺) using the three (the Direct, Bootstrap and Double Bootstrap) methods. Our aim is to illustrate the best way to estimate the ⍺-stable with (0〈⍺〈2) using simulation and real data for the daily Iraqi financial market dataset.
