Summary A general class of statistics based on sequential ranks is introduced. Under suitable regularity conditions, an almost sure representation and invariance principle are established for this class. In particular, it is shown that these statistics can obey invariance principles that are radically different from those obeyed by the usual full rank statistics.Research supported by the CSIR and the University of South AfricaResearch supported by the University of Delaware Research Foundation, Grant #8325530015 相似文献

One gives a limit theorem for the joint distribution of the stationary waiting times of customers in the queues of a multiphase queueing system, functioning in a heavy traffic regime. One proves that the joint distribution function of the waiting times is a solution of a problem with a directional derivative for an elliptic differential equation in a polyhedral angle.Translated from Veroyatnostnye Raspredeleniya i Matematicheskaya Statistika, pp. 212–229, 1986. 相似文献

We consider a large class of partially hyperbolic systems containing, among others, affine maps, frame flows on negatively curved manifolds, and mostly contracting diffeomorphisms. If the rate of mixing is sufficiently high, the system satisfies many classical limit theorems of probability theory.

Summary We prove the central limit theorem and weak invariance principle for abstract dynamical systems based on bounds on their mixing coefficients. We also develop techniques of Markov approximations for dynamical systems. We apply our results to expanding interval maps, Axiom A diffeomorphisms, chaotic billiards and hyperbolic attractors. 相似文献

Central and local limit theorems (including large deviations) are established for the number of comparisons used by the standard top-down recursive mergesort under the uniform permutation model. The method of proof utilizes Dirichlet series, Mellin transforms, and standard analytic methods in probability theory. © 1996 John Wiley & Sons, Inc. 相似文献

Stirring-exclusion processes are exclusion processes with particles being stirred. We investigate a tagged particle among a Bernoulli product environment measure on the lattice ? d .We show the strong law of large numbers and the central limit theorem for the tagged particle. The proof of the central limit theorem is based on the method of martingale decomposition with a sector condition. 相似文献

The limit theorems for polylinear forms are obtained. Conditions are found under which the distribution of the polylinear form of many random variables is essentially the same as if all the distributions of arguments were normal. 相似文献

Let T(K1,r,Gn) be the number of monochromatic copies of the r‐star K1,r in a uniformly random coloring of the vertices of the graph Gn. In this paper we provide a complete characterization of the limiting distribution of T(K1,r,Gn), in the regime where is bounded, for any growing sequence of graphs Gn. The asymptotic distribution is a sum of mutually independent components, each term of which is a polynomial of a single Poisson random variable of degree at most r. Conversely, any limiting distribution of T(K1,r,Gn) has a representation of this form. Examples and connections to the birthday problem are discussed. 相似文献

Summary The empirical measure P
n
for iid sampling on a distribution P is formed by placing mass n
–1 at each of the first n observations. Generalizations of the classical Glivenko-Cantelli theorem for empirical measures have been proved by Vapnik and ervonenkis using combinatorial methods. They found simple conditions on a class C to ensure that sup {|P
n
(C) – P(C)|: C C} converges in probability to zero. They used a randomization device that reduced the problem to finding exponential bounds on the tails of a hypergeometric distribution. In this paper an alternative randomization is proposed. The role of the hypergeometric distribution is thereby taken over by the binomial distribution, for which the elementary Bernstein inequalities provide exponential boundson the tails. This leads to easier proofs of both the basic results of Vapnik-ervonenkis and the extensions due to Steele. A similar simplification is made in the proof of Dudley's central limit theorem forn

Limit distributions are given for both the dam content at time n and the limiting dam content in the nth dam, as n tends to infinity, for a sequence of finite dams in discrete time, under assumptions which correspond to the various cases of heavy traffic in queueing theory. The proof employed is an application of the theory of weak convergence of probability measures. 相似文献

We consider a random walk which is obtained from the simple random walk by a discrete time version of Bochner’s subordination. We prove that under certain conditions on the subordinator appropriately scaled random walk converges in the Skorohod space to the symmetric -stable process . We also prove asymptotic formula for the transition function of similar to the Pólya’s asymptotic formula for . 相似文献

It is shown that the process of vertices of the convex hull of a uniform sample from the interior of a convex polygon converges locally, after rescaling, to a strongly mixing Markov process, as the sample size tends to infinity. The structure of the limiting Markov process is determined explicitly, and from this a central limit theorem for the number of vertices of the convex hull is derived. Similar results are given for uniform samples from the unit disk. 相似文献

For a bivariate sample (Xi, Yi) of size n, let (U(x), V(x)) denote the following pair of induced extreme values: U(x) is the maximum of those Yi-values with corresponding Xi-value less than x and V(x) is the maximum of the remaining Yi-values. In the paper, we study the asymptotic behavior of the (suitably normalized) random vector (U(x), V(x)), and we consider
several cases. First, we consider nonrandom x and let x=xn so that as n→∞, xn tends to the endpoint of FX(x), or so that xn tends to x0, a point in the support of FX(x). The second important situation appears when x=Xk∶n, i.e., we select Y-values on the basis of the random variable Xk∶n, the k-th order-statistic of the X-sample. Here we also consider two cases: (i) k=n−j with fixed j, and (ii) k=[np], where
0<p<1. The paper generalizes the earlier results of David, Joshi, and Nagaraja, where it is assumed that (X, Y) is in the
bivariate (max-) domain of attraction of a bivariate stable law with independent marginals.
