consistency

摘要： Although the isogeometric collocation(IGA-C)method has been successfully utilized in practical applications due to its simplicity and efficiency,only a little theoretical results have been established on the numerical analysis of the IGA-C method.In this paper,we deduce the convergence rate of the consistency of the IGA-C method.Moreover,based on the formula of the convergence rate,the necessary and sufficient condition for the consistency of the IGA-C method is developed.These results advance the numerical analysis of the IGA-C method.

摘要： Once invertibility for a causal TARMA series is defined and accompanied by conditions on the probability parameters of the model, all focus concentrates on the maximum likelihood estimators. Under the coexistence of essential causality and invertibility, the estimators are shown to be convergent to the real values and asymptotically obedient to the Gaussian distribution: their variance matrix identifies with a classic result. Some real-like examples are simulated and simplification attempts include the derivation of the non-parametric chi-square test extension for stationary TAR series.

摘要： Suppose we have a sample of subjects in two treatment groups.To study the difference of the treatment effects,we can analyse the data using all subjects(overall analysis).We may also divide the subjects into several subgroups based on some covariates of interest(eg,gender),and study the treatment effects within each subgroup.The results of these two analyses may be different or even in opposite directions.In this paper,we give a general sufficient condition of consistency between the overall and subgroup analyses.

摘要： Dear editor,Arc consistency(AC)[1]is currently the most popular local consistency for solving constraint satisfaction problems(CSP).To solve CSPs more efficiently,extensive work[2–4]has been done to find local consistencies that perform better than AC.Efforts have primarily been focused on consistencies that are stronger than AC.Even though a stronger consistency is able to eliminate more inconsistent values than AC,enforcing a stronger consistency is more expensive.It is never easy to determine the optimal tradeoff between a consistency’s pruning ability and its propagation cost.

摘要： Integrity is the quality of having strong ethical principles that are followed at all times.__and trust are central to integrity,as is consistency.“Integrity”is defined as“adherenee to moral and ethical principles;honesty”.The key to integrity is consistency-not only setting high personal standards for oneself(honesty,responsibility,respect for others,fairness)but also living up to those standards each day.One who has integrity is bound by and follows moral and ethical standards even when making life''s hard choices,choices which may be clouded by stress,pressure to__,or temptation.

摘要： In this note we consider some basic, yet unusual, issues pertaining to the accuracy and stability of numerical integration methods to follow the solution of first order and second order initial value problems (IVP). Included are remarks on multiple solutions, multi-step methods, effect of initial value perturbations, as well as slowing and advancing the computed motion in second order problems.

摘要： In this article, we focus on the semi-parametric error-in-variables model with missing responses: , where yi are the response variables missing at random, are design points, ζi are the potential variables observed with measurement errors μi, the unknown slope parameter ß?and nonparametric component g(·) need to be estimated. Here we choose two different approaches to estimate ß?and g(·). Under appropriate conditions, we study the strong consistency for the proposed estimators.

摘要： The bane of achieving a scalable distributed file sharing system is the centralized data system and single server oriented file [sharing] system. In this paper, the solution to the problems in a distributed environment is presented. Thus, inability to upload sizeable files, slow transportation of files, weak security and lack of fault tolerance are the major problems in the existing system. Hence, the utmost need is to build a client-server network that runs on two or more server systems in order to implement scalability, such that when one server is down, the other(s) would still hold up the activities within the network. And to achieve this reliable network environment, LINUX network operating system is recommended among others as a preferred platform for the synchronization of the server systems, such that every user activity like sending of internal memos/mails, publication of academic articles, is replicated;thereby, achieving the proposed result. Hence, Scalable Distributed File Sharing System provides the robustness required to having a reliable intranet.

摘要： Conditional Value-at-Risk (CVaR) is one of the commonly used risk measures. The paper shows that the optimal estimator of CVaR is strong consistency if the first-order moment of the population exists. We subsequently carry out numerical simulations to test the conclusion. We use the results to make an empirical analysis of Shenzhen A shares.
