Short course on Lévy Processes - Part 2

Ester Mariucci, Universtiät Potsdam room 2.14.0.47 from 14:15 - 15:45 and room 2.28.0.108 from 16:15 - 17:4514:15 - 16:45

Part 2: Statistics for jump processes

In the second part of the mini course, we will discuss how to estimate the Lévy measure from discrete observations of a trajectory of a Lévy process. At first, we will use the Lévy-Itô decomposition to estimate the jump part of the process in a high frequency regime, i.e. when the distance in time between the n given observations vanishes as n grows. Then, we will investigate the low frequency regime, i.e. when the trajectory of the process is sampled at a fixed rate, and estimate the Lévy measure by using a spectral approach based on the Lévy-Khintchine formula.
