15 صفحه اولModerate Deviations Type Evaluation for Integral Functionals of Diffusion Processes
where Ψ and g are smooth functions, ξε t is a “fast” ergodic diffusion whileXε t is a “slow” diffusion type process, κ ∈ (0, 1/2). Under the assumption that g has zero barycenter with respect to the invariant distribution of the fast diffusion, we derive the main result from the moderate deviation principle for the family (ε−κ ∫ t 0 g(ξ ε s)ds)t≥0, ε ↘ 0 which has an independent interest as wel...
متن کاملMoving Average Processes with Infinite Variance
The sample autocorrelation function (acf) of a stationary process has played a central statistical role in traditional time series analysis, where the assumption is made that the marginal distribution has a second moment. Now, the classical methods based on acf are not applicable in heavy tailed modeling. Using the codifference function as dependence measure for such processes be shown it be as...
متن کاملSmall Deviations of Weighted Fractional Processes and Average Non–linear Approximation
We investigate the small deviation problem for weighted fractional Brownian motions in Lq–norm, 1 ≤ q ≤ ∞. Let BH be a fractional Brownian motion with Hurst index 0 < H < 1. If 1/r := H + 1/q, then our main result asserts lim ε→0 ε log P (∥∥∥ρBH∥∥∥ Lq(0,∞) < ε ) = −c(H, q) · ‖ρ‖ Lr(0,∞) , provided the weight function ρ satisfies a condition slightly stronger than the r– integrability. Thus we e...
متن کاملProcess Level Moderate Deviations for Stabilizing Functionals
Functionals of spatial point process often satisfy a weak spatial dependence condition known as stabilization. In this paper we prove process level moderate deviation principles (MDP) for such functionals, which is a level-3 result for empirical point fields as well as a level2 result for empirical point measures. The level-3 rate function coincides with the so-called specific information. We s...
