近年来,由北京、天津和河北北部地区组成的“大北京”经济圈的规划对京津冀产业结构调整和主导产业选择都带来了新的机遇和挑战,如何根据京津冀的实际状况和产业梯度转移规律提出三地新的产业发展方向、产业转移和产业结构调整对策,就成为目前的一项迫切任务。河北经贸大学戴宏伟教授主持的国家社科基金项目的最终成果——《区域产业转移研究——以“大北京”经济圈为例》一书,立足产业梯度转移规律,以“大北京”经济圈为例对区域产业转移问题进行了系统的研究,并根据京津冀三省市产业结构的实际状况,对“大北京”经济圈产业梯度转移与产业… 相似文献

We propose an easy to derive and simple to compute approximate least squares or maximum likelihood estimator for nonlinear
errors-in-variables models that does not require the knowledge of the conditional density of the latent variables given the
observables. Specific examples and Monte Carlo studies demonstrate that the bias of this approximate estimator is small even
when the magnitude of the variance of measurement errors to the variance of measured covariates is large.

We argue that robust statistics has multiple goals, which are not always aligned. Robust thinking grew out of data analysis
and the realisation that empirical evidence is at times supported merely by one or a few observations. The paper examines
the outgrowth from this criticism of the statistical method over the last few decades.

Reversed preservation properties of some negative aging conceptions are developed for the parallel and series system which
are composed of independent and identical elements. If the system is of NWU(2) (IMRL, NWUC) properties then the elements is
also of NWU(2) (IMRL, NWUC) properties. Reversed preservation properties of the right spread order and the total time on test
transform order under the taking of maxima and minima are investigated respectively, applications in moments of NBUE ordered
populations is presented as well.

This paper presents a general algorithm tor assessing the distributional assumptions. Empirical distributions of the corresponding test statistics are obtained and examples are given to illustrate various applications of the proposed test. By using the squared radii and angles, it is shown that the problem of assessing multivariate normality can be reduced to that of testing for a univariate distribution. A limited comparison is made to investigate the power of the proposed test. This work was supported in part by the National Science Foundation under Grant NO.G88135.

Alternative boundaries for CUSUM tests 总被引:1,自引:0,他引:1
Alternative boundaries for the common Recursive (or Standard) CUSUM test and the OLS-based CUSUM test for structural change
are suggested and their properties are examined by simulation of expectedp values. The poor power of the tests for early and late structural changes can be improved for the OLS-based version, whereas
this weakness of the Recursive CUSUM test cannot be overcome by the new boundaries.

This paper developed an exact method of random permutations when testing both interaction and main effects in the two-way
ANOVA model. The method of this paper can be regarded as a much improved model when compared with those of the previous studies
such as Still and White (1981) and ter Braak (1992). We further conducted a simulation experiment in order to check the statistical
performance of the proposed method. The proposed method works relatively well for small sample sizes compare with the existing
methods.

Summary Microaggregation by individual ranking is one of themost commonly applied disclosure control techniques for continuous microdata.
The paper studies the effect of microaggregation by individual ranking on the least squares estimation of a multiple linear
regression model. It is shown that the traditional least squares estimates are asymptotically unbiased. Moreover, the least
squares estimates asymptotically have the same variances as the least squares estimates based on the original (non-aggregated)
data. Thus, asymptotically, microaggregation by individual ranking does not result in a loss of efficiency in the least squares
estimation of a multiple linear regression model.
