[图书][B] Self-normalized processes: Limit theory and Statistical Applications

VH Peña, TL Lai, QM Shao - 2009 - Springer
Self-normalized processes are of common occurrence in probabilistic and statistical studies.
A prototypical example is Student's t-statistic introduced in 1908 by Gosset, whose portrait is …

Uniform change point tests in high dimension

M Jirak - The Annals of Statistics, 2015 - projecteuclid.org
Consider $ d $ dependent change point tests, each based on a CUSUM-statistic. We
provide an asymptotic theory that allows us to deal with the maximum over all test statistics …

Cramér type moderate deviation theorems for self-normalized processes

QM Shao, WX Zhou - 2016 - projecteuclid.org
Cramér type moderate deviation theorems quantify the accuracy of the relative error of the

Self-normalized limit theorems: A survey

QM Shao, Q Wang - 2013 - projecteuclid.org
Abstract Let X_1,X_2,..., be independent random variables with EX_i=0 and write
S_n=i=1^nX_i and V_n^2=i=1^nX_i^2. This paper provides an overview of current …

Bootstrapping nonstationary autoregressive processes with predictive regression models

C Katsouris - arXiv preprint arXiv:2307.14463, 2023 - arxiv.org
We establish the asymptotic validity of the bootstrap-based IVX estimator proposed by
Phillips and Magdalinos (2009) for the predictive regression model parameter based on a …

Convergence rates for probabilities of moderate deviations for moving average processes

PY Chen, DC Wang - Acta Mathematica Sinica, English Series, 2008 - Springer
The present paper first shows that, without any dependent structure assumptions for a
sequence of random variables, the refined results of the complete convergence for the …
