Abstract

This talk aims at surveying some of the recent developments of nonstationary and long-memory time series. The underlying theme of recent endeavour arises from the consideration of the order of magnitude of the observed Fisher's information number. By means of a simple AR(1) model, the so-called “SNoTE”, it is shown how this number affects the nonstationary behaviour in a subtle and important way. The talk concludes with the discussion of some of the recent results involving negative moment bounds of the observed Fishers' information number and their applications to multi-step ahead predictions.
