On limit theory for functionals of stationary increments Lévy driven moving averages

Research output: Contribution to journal/Conference contribution in journal/Contribution to newspaperJournal articleResearchpeer-review

In this paper we present new limit theorems for variational functionals of stationary increments Levy driven moving averages in the high frequency setting. More specifically, we will show the "law of large numbers'' and a "central limit theorem'', which heavily rely on the kernel, the driving Levy process and the properties of the functional under consideration. The first order limit theory consists of three different cases. For one of the appearing limits, which we refer to as the ergodic type limit, we prove the associated weak limit theory, which again consists of three different cases. Our work is related to a recent work on power variation functionals of stationary increments Levy driven moving averages. However, the asymptotic theory of the present paper is more complex. In particular, the weak limit theorems are derived for an arbitrary Appell rank of the involved functional.
