We show that the Truncated Realized Variance (TRV) of a SemiMartingale (SM) converges to zero when observations are contaminated by noise. Under the additive i.i.d. noise assumption, a central limit theorem is also proved. In consequence it is possible to construct a feasible test allowing us to...

This article presents a systematic and extensive empirical study on the presence of Markov switching dynamics in three dollar-based exchange rates. A Monte Carlo approach is adopted to circumvent the statistical inference problem inherent in the test of regime-switching behavior. Two data...

This study examines the frequency of sampling at contaminated sites located in heterogeneous subsurface environments. The impact of delays in remedial response is also investigated in terms of the growth that such delays incur on contaminated areas and remediation costs. Our work utilizes...
