Self-normalization for time series: a review of recent developments

X Shao - Journal of the American Statistical Association, 2015 - Taylor & Francis
This article reviews some recent developments on the inference of time series data using the
self-normalized approach. We aim to provide a detailed discussion about the use of self …

A self-normalized approach to confidence interval construction in time series

X Shao - Journal of the Royal Statistical Society Series B …, 2010 - academic.oup.com
We propose a new method to construct confidence intervals for quantities that are
associated with a stationary time series, which avoids direct estimation of the asymptotic …

Online covariance matrix estimation in stochastic gradient descent

W Zhu, X Chen, WB Wu - Journal of the American Statistical …, 2023 - Taylor & Francis
The stochastic gradient descent (SGD) algorithm is widely used for parameter estimation,
especially for huge datasets and online learning. While this recursive algorithm is popular …

Summability of stochastic processes—A generalization of integration for non-linear processes

V Berenguer-Rico, J Gonzalo - Journal of Econometrics, 2014 - Elsevier
The order of integration is valid to characterize linear processes; but it is not appropriate for
non-linear worlds. We propose the concept of summability (a re-scaled partial sum of the …

Subsampling inference for the mean of heavy‐tailed long‐memory time series

A Jach, T McElroy, DN Politis - Journal of Time Series Analysis, 2012 - Wiley Online Library
In this article, we revisit a time series model introduced by MCElroy and Politis (2007a) and
generalize it in several ways to encompass a wider class of stationary, nonlinear, heavy …

Fixed-b asymptotics for the studentized mean from time series with short, long, or negative memory

T McElroy, DN Politis - Econometric Theory, 2012 - cambridge.org
This paper considers the problem of variance estimation for the sample mean in the context
of long memory and negative memory time series dynamics, adopting the fixed-bandwidth …

A nonstandard empirical likelihood for time series

DJ Nordman, H Bunzel, SN Lahiri - The Annals of Statistics, 2013 - JSTOR
Standard blockwise empirical likelihood (BEL) for stationary, weakly dependent time series
requires specifying a fixed block length as a tuning parameter for setting confidence regions …

On the measurement and treatment of extremes in time series

T McElroy - Extremes, 2016 - Springer
The paper reviews the topic of extremal time series. The literature documenting the
presence of extremes in time series data is first reviewed, followed by a discussion of …

Spectral density and spectral distribution inference for long memory time series via fixed-b asymptotics

TS McElroy, DN Politis - Journal of Econometrics, 2014 - Elsevier
This paper studies taper-based estimates of the spectral density utilizing a fixed bandwidth
ratio asymptotic framework, and makes several theoretical contributions:(i) we treat multiple …

Kuznets curve for the US: A reconsideration using cosummability

AB Nasr, M Balcilar, SS Akadiri, R Gupta - Social Indicators Research, 2019 - Springer
The relationship between income inequality and long-run economic growth has gained a
growing attention in economic research for over decades. This study employed advanced …
