Nonparametric estimation of distribution functions

Summary Using Silverman and Young’s (1987) idea of rescaling a rescaled smoothed empirical distribution function is defined and investigated when the smoothing parameter depends on the data. The rescaled smoothed estimator is shown to be often better than the commonly used ordinary smoothed estimator.     

Consumption and stock markets in Asian economies

This paper investigates the causal links between stock market performance and consumption for five Asian economies by applying the bound tests of Pesaran et al. and lag augmented VAR of Toda and Yamamoto . We find two‐way causal relationships between stock market performance and consumption in the cases of Hong Kong and Taiwan in the long run. The existence of such two‐way causal links indicates that stock market performance and consumption mutually affect each other, implying that the previous studies may have overestimated the wealth effect of the stock markets without taking account of the reverse causation from consumption to the stock markets. The short‐run effect of the stock market on consumption is more visible than the long‐run effect in most of the sample economies, suggesting that changes in consumption directly reflect stock market fluctuations.     

Model-based control charts in phase 1 statistical process control

In this paper, a general method of constructing control charts for preliminary analysis of individual observations is presented, which is based on recursive score residuals. A simulation study shows that certain implementations of these charts are highly effective in detecting assignable causes.

翻译过程思维模式的理性探索

研究翻译过程就是探讨双语转换的认知心理过程,以揭示其思维规律。拟建的翻译模式整合Van Dijk的话语宏观结构理论和Neubert与Shreve的“虚构译本”观点,将七个语篇特征视为译者在解码与构码过程中作调整和变通的参数,旨在动态描述翻译过程。     

人力资本、物质资本与经济增长——基于中国数据的经验研究

通过测算我国改革开放以来经济发展中的物质资本存量和人力资本存量，并利用现代计量分析方法分析人力资本、物质资本与我国经济增长之间的动态相关关系，建立了三者之间的向量自回归模型以及长期均衡和短期均衡模型。分析结果表明：我国的GDP、物质资本和人力资本之间存在着长期均衡关系；虽然短期内的经济增长仍要依靠物质资本的大量投入，人力资本对经济增长的贡献较小，但从长期来看，人力资本对经济增长的贡献要大于物质资本，而且是经济增长的Granger原因。因此，我国应加大对教育的投资，提高人力资本存量。     

汇率对产业内贸易的传导和冲击效应——基于中国东盟自由贸易区的分析

本文以中国与东盟六国18类产品的产业内贸易的月度面板数据作为分析基础，通过分析汇率与产业内贸易的传导关系、中国与东盟六国产业内贸易特点，并且建立产业内贸易指数与汇率的VAk模型．对我国的汇率对产业内贸易的冲击作用和动态关系做实证分析。研究发现：一是无论是短期或长期．汇率升值对绝大多数初级产品的产业内贸易是不利的，但在短期内它有助于提升大多数工业制品的产业内贸易水平．长期内对工业制品的产业内贸易冲击效应是分化的。二是汇率升值后长期内对不同劳动密集型产品的产业内贸易发展是一样的。三是无论是短期还是长期，初级产品的产业内贸易对汇率冲击的反应相当微弱．工业制品反应相对较强。

Three Corrected Score Tests for Generalized Linear Models with Dispersion Covariates

We develop three corrected score tests for generalized linear models with dispersion covariates, thus generalizing the results of Cordeiro , Ferrari and Paula (1993) and Cribari-Neto and Ferrari (1995) . We present, in matrix notation, general formulae for the coefficients which define the corrected statistics. The formulae only require simple operations on matrices and can be used to obtain analytically closed-form corrections for score test statistics in a variety of special generalized linear models with dispersion covariates. They also have advantages for numerical purposes since our formulae are readily computable using a language supporting numerical linear algebra. Two examples, namely, iid sampling without covariates on the mean or dispersion parameter oand one-way classification models, are given. We also present some simulations where the three corrected tests perform better than the usual score test, the likelihood ratio test and its Bartlett corrected version. Finally, we present a numerical example for a data set discussed by Simonoff and Tsai (1994) .
