Clustering of large deviations in moving average processes: The long memory regime

نویسندگان

چکیده

We investigate how large deviations events cluster in the framework of an infinite moving average process with light-tailed noise and long memory. The memory makes clusters larger, asymptotic behaviour size turns out to be described by first hitting time a randomly shifted fractional Brownian motion drift.

The effect of memory on functional large deviations of infinite moving average processes

Abstract The large deviations of an infinite moving average process with exponentially light tails are very similar to those of an i.i.d. sequence as long as the coefficients decay fast enough. If they do not, the large deviations change dramatically. We study this phenomenon in the context of functional large, moderate and huge deviation principles.

Moving Average Processes with Infinite Variance

The sample autocorrelation function (acf) of a stationary process has played a central statistical role in traditional time series analysis, where the assumption is made that the marginal distribution has a second moment. Now, the classical methods based on acf are not applicable in heavy tailed modeling. Using the codifference function as dependence measure for such processes be shown it be as...

Long Strange Segments, Ruin Probabilities and the Effect of Memory on Moving Average Processes

We obtain the rate of growth of long strange segments and the rate of decay of infinite horizon ruin probabilities for a class of infinite moving average processes with exponentially light tails. The rates are computed explicitly. We show that the rates are very similar to those of an i.i.d. process as long as moving average coefficients decay fast enough. If they do not, then the rates are sig...

Prediction in moving average processes

For the stationary invertible moving average process of order one with unknown innovation distribution F , we construct root-n consistent plug-in estimators of conditional expectations E(h(Xn+1)|X1, . . . , Xn). More specifically, we give weak conditions under which such estimators admit Bahadur type representations, assuming some smoothness of h or of F . For fixed h it suffices that h is loca...
