This paper establishes the asymptotic normality of the Whittle estimator of the unknown dependence parameters in a linear regression model with long memory moving average errors. The design variables are taken to be deterministic or random. In the latter case they are assumed to have a moving average representation that includes both short and long memory. In all cases, it is observed that the rate of consistency of the regression parameter estimator has an effect on the asymptotic normality of the Whittle estimator. 相似文献

Interpolation, correlation identities, and inequalities for infinitely divisible variables 总被引:1,自引:0,他引:1

We present an interpolation formula for the expectation of functions of infinitely divisible (i.d.) variables. This is then
applied to study the association problem for i.d. vectors and to present new covariance expansions and correlation inequalities.

Recently, Philippe et al. (C.R. Acad. Sci. Paris. Ser. I 342, 269–274, 2006; Theory Probab. Appl., 2007, to appear) introduced a new class of time-varying fractionally integrated filters A(d)x t =∑ j=0 ∞ a j (t)x t?j , B(d)x t =∑ j=0 ∞ b j (t)x t?j depending on arbitrary given sequence d=(d t ,t∈?) of real numbers, such that A(d)?1=B(?d), B(d)?1=A(?d) and such that when d t ≡d is a constant, A(d)=B(d)=(1?L) d is the usual fractional differencing operator. Philippe et al. studied partial sums limits of (nonstationary) filtered white noise processes X t =B(d)ε t and Y t =A(d)ε t in the case when (1) d is almost periodic having a mean value $\bar{d}\in (0,1/2)$ , or (2) d admits limits d ±=lim? t→±∞ d t ∈(0,1/2) at t=±∞. The present paper extends the above mentioned results of Philippe et al. into two directions. Firstly, we consider the class of time-varying processes with infinite variance, by assuming that ε t ,t∈? are iid rv’s in the domain of attraction of α-stable law (1<α≤2). Secondly, we combine the classes (1) and (2) of sequences d=(d t ,t∈?) into a single class of sequences d=(d t ,t∈?) admitting possibly different Cesaro limits $\bar{d}_{\pm}\in(0,1-(1/\alpha))$ at ±∞. We show that partial sums of X t and Y t converge to some α-stable self-similar processes depending on the asymptotic parameters $\bar{d}_{\pm}$ and having asymptotically stationary or asymptotically vanishing increments. 相似文献

This paper considers the problem of testing a sub-hypothesis in homoscedastic linear regression models when the covariate
and error processes form independent long memory moving averages. The asymptotic null distribution of the likelihood ratio
type test based on Whittle quadratic forms is shown to be a chi-square distribution. Additionally, the estimators of the slope
parameters obtained by minimizing the Whittle dispersion is seen to be n
1/2-consistent for all values of the long memory parameters of the design and error processes.
