Improving on truncated linear estimates of exponential and gamma scale parameters

We consider the problem of estimating the scale parameter of an exponential or a gamma distribution under squared error loss when the scale parameter θ is known to be greater than some fixed value θ₀. Natural estimators in this setting include truncated linear functions of the sufficient statistic. Such estimators are typically inadmissible, but explicit improvements seem difficult to find. Some are presented here. A particularly interesting finding is that estimators which are admissible in the untruncated problem which take values only in the interior of the truncated parameter space are found to be inadmissible for the truncated problem.     

《唐摭言》成书时间考

唐五代著名的笔记小说《唐摭言》专述有唐一代之科举之人事,有丰富的史料价值。但此书成书时间历来所论不一,本文试以《唐摭言》文本为据,在有关前人论述的基础上再详加考述,初步推定为南汉大有初或大有中王定保任宁远节度使期间所撰。

Model Uncertainty and Bayesian Model Averaged Benchmark Dose Estimation for Continuous Data

The benchmark dose (BMD) approach has gained acceptance as a valuable risk assessment tool, but risk assessors still face significant challenges associated with selecting an appropriate BMD/BMDL estimate from the results of a set of acceptable dose‐response models. Current approaches do not explicitly address model uncertainty, and there is an existing need to more fully inform health risk assessors in this regard. In this study, a Bayesian model averaging (BMA) BMD estimation method taking model uncertainty into account is proposed as an alternative to current BMD estimation approaches for continuous data. Using the “hybrid” method proposed by Crump, two strategies of BMA, including both “maximum likelihood estimation based” and “Markov Chain Monte Carlo based” methods, are first applied as a demonstration to calculate model averaged BMD estimates from real continuous dose‐response data. The outcomes from the example data sets examined suggest that the BMA BMD estimates have higher reliability than the estimates from the individual models with highest posterior weight in terms of higher BMDL and smaller 90th percentile intervals. In addition, a simulation study is performed to evaluate the accuracy of the BMA BMD estimator. The results from the simulation study recommend that the BMA BMD estimates have smaller bias than the BMDs selected using other criteria. To further validate the BMA method, some technical issues, including the selection of models and the use of bootstrap methods for BMDL derivation, need further investigation over a more extensive, representative set of dose‐response data.     

基于盾构掘进参数的LVQ神经网络地层识别

以苏州4号线2标及2号线东延伸线5标地铁工程为背景，分析了盾构机的掘进参数：千斤顶推力、推进速度、刀盘扭矩、螺旋机转速和同步注浆量在不同地层条件下的变化规律。提出了基于盾构机掘进参数的学习向量量化（Learning Vector Quantization，LVQ）神经网络地层识别方法。建立了以盾构机五个掘进参数作为输入，地层特性编码为输出的数学模型，通过每种地层100组训练样本对模型进行训练，通过57步训练，训练样本误差控制在0.1以内，并用每种地层50组检验样本进行检验，地层总体识别率达到82.7%。     

中国特色社会主义民主政治的内在优势和前景

所谓中国模式、中国奇迹,从表象来看是中国经济发展的奇迹,实际上其背后的支撑是中国政治制度的优势。中国经济奇迹的秘密在于我们的政治制度的有效性和优越性,他能组织和调动起八千多万党员和13亿人民的积极性和创造性;能为现代化目标做出长远规划,且能在动态中加以调整;能确保改革开放在和谐稳定的环境中逐步推进;有足够的组织上的激励去执行和维护经济发展的战略;能推动国家和社会的良性互动;为各级地方政府间互相竞争提供可持续的学习和创新平台;在面对国际国内危机时善于化危机为机遇。     

血墨丹青--恽寿平生平艺术初探

清代初期画坛六大家之一的恽寿平,早年抗清,失败后誓不入仕,隐居武进老宅,倾情诗书画,既为谋生,亦是萌志。中年赁居常州城中白云溪畔,先借画室,后扩为家,并终老于此。文章阐述了他与另一书画大师王翚艺术互慕、事业相助的终生友谊,总结了其绘画艺术特色,即独创“没骨花卉”技法,并引领“常州画派”风靡清代早中期神州画坛。
