VAR系统——一种宏观经济预警的新方法

VAR系统（Vector Autoregressive System）是西姆斯（Sims）于1980年提出的一种新型的宏观经济计量模型。由于该模型具有若干突出优点,在国际上得到了日益广泛的应用,并有逐步取代传统宏观经济模型的趋势。本文对VAR系统做简要介绍,进而利用山西省的统计资料构造一个简单的宏观经济分析、预警模型。     

Goodness—of—fit for the two—parameter weibull distribution with estimated parameters

Goodness—of—fit statistics based on the empirical distribution function (EDF) are not distribution—free when parameters for the hypothesized distribution are estimated. Tables are percentile values of several EDF statistics are available for the two—parameter Weibull distribution when parameters are estimated by maximum likelihood. To determine how these tabled values change when simpler estimators are employed, percentile scores for EDF goodness—of—fit tests were obtained by Monte—Carlo simulation for maximum likelihood estimators (MLEs), good linear unbiased estimators (GLUEs), and modified Cramer—von Mises, Anderson—Darling, and Watson statistics are presented for GLUEs for both complete and censored samples. Critical values for Kolmogorov—Smirnov statistics were less affected by the method of estimation than were closer for MLEs and MGLUEs than for MGLUEs and GLUEs. On the other hand, MGLUE and GLUE results were much more similar to each other than to the MLE results when censoring was light and sample sizes were large.     

Cointegration testing under structural change: reducing size distortions and improving power of residual based tests

This paper investigates how standard residual based tests for cointegration—under structural change in the long run relationship—can be modified in order to reduce size distortions and improve power, by following the same ideas used in the unit root context. This is a natural strategy given that these tests are unit root statistics applied to estimated residuals from a cointegrating regression. In order to assess the finite sample performance of the alternative tests, a Monte Carlo experiment will be implemented to analyze size and power. Critical values for the tests constructed with GLS detrended data, proposed by Elliot et al. (Econometrica 64:813–836, 1996), are obtained by simulation.     

Bias in Routine Calculation of the Variance of OLS Estimators When the Disturbances are Autocorrelated

In this article a sequence of statistical games is described that were found useful for teaching statistics to agriculture students. The ideas of experimental design tend to be neglected in statistics service courses for agriculturalists because of the practical difficulty of allowing students to learn design by experience. Simulating experiments in the classroom or on the computer console is a viable alternative and should be more widely used. In this article, three games—TOMATO, CHICK, and SELECT—are described. Other games can be invented. The relevance of using games extends to fields other than agriculture.     

面板数据模型的截面相关检验研究

 相关系数的绝对值形式可以很好的避免Pesaran（2004）的CD统计量中异向相关性相互抵消的情况,相应得到一个新的检验面板数据模型扰动项截面相关的统计量。蒙特卡洛模拟显示,无论是在因子模型下还是在空间移动平均模型下,新提出的统计量水平扭曲(size distortion)检验和功效(power)检验表现较好。通过模拟还发现当存在序列相关的扰动项时,先将扰动项进行去序列相关处理可以有效地避免序列相关导致的水平扭曲,并且不会降低统计量的功效。     

The union-intersection principle applied to the test of dimensionality

In the first section Anderson-Rao-Fujikoshi's test statistics for testing the hypothesis of dimensionality are reviewed and then Olkin-Tomsky's generalized union-intersection principle is applied to show that a new class of test statistics for testing the hypothesis of dimensionality are derived which includes the likelihood ratio test statistics, the trace test statistics and a version of ROY'S maximum root test statistics.     

Neural networks and flexible regression and discrimination

Feed-forward neural networks—also known as multi-layer perceptrons—are now widely used for regression and classification. In parallel but slightly earlier, a family of methods for flexible regression and discrimination were developed in multivariate statistics, and tree-induction methods have been developed in both machine learning and statistics. We expound and compare these approaches in the context of a number of examples.

Goodness-of-fit Procedures for Copula Models Based on the Probability Integral Transformation

Abstract.  Wang & Wells [ J. Amer. Statist. Assoc. 95 (2000) 62] describe a non-parametric approach for checking whether the dependence structure of a random sample of censored bivariate data is appropriately modelled by a given family of Archimedean copulas. Their procedure is based on a truncated version of the Kendall process introduced by Genest & Rivest [ J. Amer. Statist. Assoc. 88 (1993) 1034] and later studied by Barbe et al . [ J. Multivariate Anal. 58 (1996) 197]. Although Wang & Wells (2000) determine the asymptotic behaviour of their truncated process, their model selection method is based exclusively on the observed value of its L ²-norm. This paper shows how to compute asymptotic p -values for various goodness-of-fit test statistics based on a non-truncated version of Kendall's process. Conditions for weak convergence are met in the most common copula models, whether Archimedean or not. The empirical behaviour of the proposed goodness-of-fit tests is studied by simulation, and power comparisons are made with a test proposed by Shih [ Biometrika 85 (1998) 189] for the gamma frailty family.     

A Note on the Geometric Representation of the Correlation Coefficients

Four widely used statistical program packages—BMDP, SPSS, DATATEXT, and OSIRIS—were compared for computational accuracy on sample means, standard deviations, and correlations. Only one, BMDP, was not seriously inaccurate in calculations on a data set of three observations. Further, SPSS computed inaccurate statistics in a discriminant analysis on a real data set of 848 observations. It is recommended that the desk calculator algorithm, found in most of these programs, not be used in packages which may run on short word length machines.
