Weak convergence of Vervaat and Vervaat Error processes of long-range dependent sequences
Following Cs\"{o}rg\H{o}, Szyszkowicz and Wang (Ann. Statist. {\bf 34},
(2006), 1013--1044) we consider a long range dependent linear sequence. We
prove weak convergence of the uniform Vervaat and the uniform Vervaat error
processes, extending their results to distributions with unbounded support and
removing normality assumption
Reduction principles for quantile and Bahadur-Kiefer processes of long-range dependent linear sequences
In this paper we consider quantile and Bahadur-Kiefer processes for long
range dependent linear sequences. These processes, unlike in previous studies,
are considered on the whole interval . As it is well-known, quantile
processes can have very erratic behavior on the tails. We overcome this problem
by considering these processes with appropriate weight functions. In this way
we conclude strong approximations that yield some remarkable phenomena that are
not shared with i.i.d. sequences, including weak convergence of the
Bahadur-Kiefer processes, a different pointwise behavior of the general and
uniform Bahadur-Kiefer processes, and a somewhat "strange" behavior of the
general quantile process.Comment: Preprint. The final version will appear in Probability Theory and
