| Abstract | Statistical inference of long-memory time series faces two challenges due to the special behavior of the sample sum 1) a non-standard fluctuation rate which is typically unknown 2) a family of non-Gaussian scaling limits arise and it is difficult to determine which one is involved statistically. We introduce a procedure which combines two strategies: self-normalization and subsampling. Such a combination successfully bypasses the aforementioned challenges.

For such cases of locally stationary time series (LSTS) the Model-Free (MF) Prediction Principle developed by Politis (2013) can be used for predictive inference. The MF principle permits analysis of such series in very general cases which may include a trend and time-varying mean, variance, higher-order moments or nonstationarity in the mth order marginal distribution. Based on various nonstationarity properties of such LSTS several one-step ahead point prediction and prediction interval generation methods are developed and their performance compared using finite sample simulations. |
