The ordinary Wilcoxon signed rank test table provides confidence intervals for the median of one population. Adjusted Wilcoxon signed rank test tables which can provide confidence intervals for the median and the 10th percentile of one population are created in this paper. Base-(n + 1) number system and theorems about property of symmetry of the adjusted Wilcoxon signed rank test statistic are derived for programming. Theorem 1 states that the adjusted Wilcoxon signed rank test statistic are symmetric around n(n + 1)/4. Theorem 2 states that the adjusted Wilcoxon signed rank test statistic with the same number of negative ranks m are symmetric around m(n+1)/2. 87.5% and 85% confidence intervals of the median are given in the table for n = 12, 13,…, 29 to create approximated 95% confidence intervals of the ratio of medians for two independent populations. 95% and 92.5% confidence intervals of the 10th percentile are given in the table for n = 26, 27, 28, 29 to create approximated 95% confidence regions of the ratio of the 10th percentiles for two independent populations. Finally two large datasets from wood industry will be partitioned to verify the correctness of adjusted Wilcoxon signed rank test tables for small samples. 相似文献

ABSTRACTIn a model of tuberculosis with relapse, the basic reproduction number R0 includes new and relapse infections. Lyapunov functions help to prove that the global dynamic is completely determined by R0. Replicated Latin hypercube sampling shows that early diagnosis and treatment are more efficient when relapse cases are considered. 相似文献

In consumer preference studies, it is common to seek a complete ranking of a variety of, say N, alternatives or treatments. Unfortunately, as N increases, it becomes progressively more confusing and undesirable for respondents to rank all N alternatives simultaneously. Moreover, the investigators may only be interested in consumers’ top few choices. Therefore, it is desirable to accommodate the setting where each survey respondent ranks only her/his most preferred k (k?N) alternatives. In this paper, we propose a simple procedure to test the independence of N alternatives and the top-k ranks, such that the value of k can be predetermined before securing a set of partially ranked data or be at the discretion of the investigator in the presence of complete ranking data. The asymptotic distribution of the proposed test under root-n local alternatives is established. We demonstrate our procedure with two real data sets. 相似文献

Although new transmuted distributions have been widely proposed in the last few years, it is rarely to find those class of models applied in survival analysis in the presence of censored lifetimes. In this context, we are concerned in applying the transmuted log-logistic model in the study of discharge times of patients treated with the Linezolid drug. For model fitting, we use and compare different profile likelihood methods. Analysis of residuals and influence are also presented. All results are validated in a simulation study by considering the bootstrap techniques. 相似文献

《江泽民文选》中包含了多篇关于反腐倡廉的重要论述,形成了完整的江泽民反腐倡廉理论体系,纪检监察干部应认真学习《江泽民文选》,用江泽民反腐倡廉理论武装头脑,指导实践。加强纪检监察干部队伍思想政治建设,要始终做到“三个坚定不移”;加强纪检监察干部能力建设,应提高“五种能力”;加强纪检监察机关作风建设,要树立“五种形象”。 相似文献

中国古代儒家"用夏变夷"思想与理论的变迁 总被引:1,自引:0,他引:1

“用夏变夷”是儒家民族思想的重要组成部分,从孟子首次提出后,随着社会历史的变迁,其精神实质和具体内涵无论在理论上还是在实践中都发生了一些变化。大体说来,它经历了从孔子时的“夷而进于中国则中国之”到孟子时提出“用夏变夷”的思想;从先秦时的“外夷狄”、“正朔所不加”到汉唐时的“华夷一统”、“夷狄进至于爵”;从先秦汉唐时的“不予夷狄之主中国”到金元时的“能行中国之道则中国之主也”几个阶段。 相似文献

AbstractSmall area estimation techniques have got a lot of attention during the last decades due to their important applications in survey studies. Mixed linear models and reduced rank regression analysis are jointly used when considering small area estimation. Estimates of parameters are presented as well as prediction of random effects and unobserved area measurements. 相似文献

In the present investigation, the unconditional asymptotic distribution of a class of aligned rank order test statistics for randomized block designs is derived under the null hypothesis and for nearby alternatives, as the number of blocks tends to infinity. The proofs of these results are based on the asymptotic equivalence in quadratic mean between aligned observations and their ranks and thus are quite similar to the Hájek and SKidák (1967) approach. 相似文献
