Limit theorems for moving averages of discretized processes plus noise

چکیده
This paper presents some limit theorems for certain functionals of moving averages of semimartingales plus noise, which are observed at high frequency. Our method generalizes the pre-averaging approach (see [13],[11]) and provides consistent estimates for various characteristics of general semimartingales. Furthermore, we prove the associated multidimensional (stable) central limit theorems. As expected, we find central limit theorems with a convergence rate n−1/4, if n is the number of observations.

Background and aims: Noise pollution is one of the risk factors of the human environment that may seriously threat physical and mental health of human beings. One of the main sources of this type of pollution is the noise produced by urban transportation and traffic, particularly subway in the environment. This article aims at study and evaluation of the noise condition in drivers’ cabin and ...
متن کامل2 Almost Sure Limit Theorems for Expanding Maps of the Interval
For a large class of expanding maps of the interval, we prove that partial sums of Lipschitz observables satisfy an almost sure central limit theorem (ASCLT). In fact, we provide a speed of convergence in the Kantorovich metric. Maxima of partial sums are also shown to obey an ASCLT. The key-tool is an exponential inequality recently obtained. Then we derive almost-sure convergence rates for th...
متن کاملEstimating Customer and Time Averages
In this paper we establish a joint central limit theorem for customer and time averages by applying a martingale central limit theorem in a Markov framework. The limiting values of the two averages appear in the translation terms. This central limit theorem helps to construct confidence intervals for estimators and perform statistical tests. It thus helps determine which finite average is a mor...
متن کاملAdditive Functionals of Infinite-variance Moving Averages
We consider the asymptotic behavior of additive functionals of linear processes with infinite variance innovations. Applying the central limit theory for Markov chains, we establish asymptotic normality for short-range dependent processes. A non-central limit theorem is obtained when the processes are long-range dependent and the innovations are in the domain of attraction of stable laws.
