Estimated Data Collection Organization Effect in the National Medical Care Expenditure Survey

The National Medical Care Expenditure Survey, which has a complex survey design, is further complicated by combining two independently drawn national samples of households from the Research Triangle Institute (RTI) and the National Opinion Research Center (NORC). It is assumed that since the structures of these national-area samples are similar, they are thereby compatible and allow for the derivation of statistically equivalent unbiased national estimates of relevant health parameters. In this paper, national parameter estimates of relevant demographic and health measures were separately produced for each of the two survey organizations and a determination was made regarding statistical equivalence across samples. In addition, the data-collection organization effect was estimated and tested within the framework of a multivariate analysis appropriate for complex survey data. The findings consistently revealed a statistically nonsignificant data-collection organization effect when testing for differences in domain estimates of the relevant health parameters under consideration.     

房价变动、产业转移与区域协调发展——以京津冀地区为例

构建房价-资本模型，分析房地产行业投资收益对工业再投资的影响，发现：地区间适当的房地产行业投资收益差异有利于工业企业从核心地区向边缘地区转移，差异较大则导致资本流向房价增长过快地区的房地产行业；若地区间房地产行业投资收益差异既定，较大的经济发展差距对产业转移起阻碍作用，激烈的市场竞争则起促进作用。利用京津冀地区13个城市的数据构建面板门限模型，验证了：（1）较低的房价增长率促进了北京市相对低效的资本向外转移，但是北京市与周边地区较大的经济发展差距又阻碍了该趋势。（2）核心区流出的资本优先向次发达地区转移，而落后地区则有被彻底边缘化的风险。为实现京津冀地区协调发展，一方面要加强对京津冀地区房价的宏观调控、防止房价过快增长；另一方面要制定针对边缘地区的优惠政策，引导非首都功能向周边转移。

A note on Läuter-type robust design for polynomial regression models

In this paper, we consider the problem of model robust design for simultaneous parameter estimation among a class of polynomial regression models with degree up to k. A generalized D-optimality criterion, the Ψ_α‐optimality criterion, first introduced by Läuter (1974) is considered for this problem. By applying the theory of canonical moments and the technique of maximin principle, we derive a model robust optimal design in the sense of having highest minimum Ψ_α‐efficiency. Numerical comparison indicates that the proposed design has remarkable performance for parameter estimation in all of the considered rival models.     

A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.     

土地价格、房地产开发投资对房价影响的实证分析

针对土地价格、房地产开发投资对房价的影响,依据2000—2010年间的中国居住用途土地价格、房地产开发投资完成额和商品房价格的年度数据,运用协整检验和误差修正模型进行了实证研究。结果表明:我国的房地产价格与土地价格、房地产开发投资额之间存在长期稳定的均衡关系;土地价格是房价变动的促进因素,而房地产开发投资额变动对房价的影响更为显著。     

Strong Consistency of Conditional Value-at-risk Estimate for ϕ-mixing Samples

In this article, we investigate the strong consistency of conditional value-at-risk estimate for ? ?mixing samples under mild conditions. Moreover, the corresponding strong consistency rate is also obtained.
