Some tests for the power series distibutions in one parameter using the kullback-leibler information measure

The purpose of the article is, in case of one sample, to obtain tests concerning the parameter in the power series distribution in one parameter using Ku11back-Leibier information measure. The class of power series distibutions contains a host of discrete distributions. Ve illustrate the general results obtained in case of the geometric distibution.     

Dempster's combination rule and sufficient statistics

In his articles (1966-1968) concerning statistical inference based on lower and upper probabilities, Dempster refers to the connection between Fisher's fiducial argument and his own ideas of statistical inference. Dempster's main concern however focuses on the “Bayesian” aspects of his theory and not on an elaboration of the relation between Fisher's and his ideas. This article attempts to work out the connection between those two approaches and focuses primarily on the question, whether Dempster's combination rule, his upper and lower probabilty based on sufficient statistics and inference based on sufficient statistics in Fisher's sense are consistent. To be adequate to Fisher's reasoning, we deal with absolutely continuous, one parametric families of distributions.This is certainly not the usual assumption in context with Dempster's theory and implies a normative but straightforward definition concerning the underlying conditional distribution; this definition however is done in Dempster's spirit as can be seen from his articles, (1966, 1968,a,b). Under those assumptions it can be shown that - similar to Lindley's results concerning consistency in fiducial reasoning (1958) - the combination rule, Dempster's procedure based on sufficient statistics and fiducial inference by sufficient statistics agree iff the parametric family under consideration can be transformed to location parameter form.     

An exact test for nbue class of survival functions

Let F(x) be a life distribution. An exact test is given for testing H₀ F is exponential, versusH₁Fε NBUE (NWUE); along with a table of critical values for n=5(l)80, and n=80(5)65. An asymptotic test is made available for large values of n, where the standardized normal table can be used for testing.     

Nonparametric density deconvolution by weighted kernel estimators

Nonparametric density estimation in the presence of measurement error is considered. The usual kernel deconvolution estimator seeks to account for the contamination in the data by employing a modified kernel. In this paper a new approach based on a weighted kernel density estimator is proposed. Theoretical motivation is provided by the existence of a weight vector that perfectly counteracts the bias in density estimation without generating an excessive increase in variance. In practice a data driven method of weight selection is required. Our strategy is to minimize the discrepancy between a standard kernel estimate from the contaminated data on the one hand, and the convolution of the weighted deconvolution estimate with the measurement error density on the other hand. We consider a direct implementation of this approach, in which the weights are optimized subject to sum and non-negativity constraints, and a regularized version in which the objective function includes a ridge-type penalty. Numerical tests suggest that the weighted kernel estimation can lead to tangible improvements in performance over the usual kernel deconvolution estimator. Furthermore, weighted kernel estimates are free from the problem of negative estimation in the tails that can occur when using modified kernels. The weighted kernel approach generalizes to the case of multivariate deconvolution density estimation in a very straightforward manner.     

五四新文化运动与欧洲文艺复兴运动比较

五四新文化运动与欧洲文艺复兴运动生成于不同时期,植根于不同土壤,二者既有一些共同之处,又有不少差异。对其进行比较,有助于加深我们对两个运动各自特性的认识。其共同点是：（一）对传统的批判与重建;（二）倡导文学革命;（三）抨击封建权威思想;（四）呼唤人性的复苏,倡导个人的解放。其不同点是：（一）背景不同;（二）影响力不同;（三）带来的后果不同。     

通过政绩考察干部的品、志、谋、能、器

在干部的考察中,不仅要考察干部的政绩,而且要善于通过政绩来考察干部的"官品"、"志趣"、"谋断"、"能力"和"大器"等方面的素质,以便更全面、更深入地了解干部,避免和克服干部考察中的形而上学和片面倾向,以匡正不良的用人之风.     

以孔子体育教育思想为镜观中国教育思想中轻体的痼疾

孔子的教育思想影响中国两千年,但由于历史的错误,其光辉的体育教育思想一度被淹没,面对当今轻体思潮依然严重的现状,我们有必要还孔子体育教育思想以本来面目,并借以抨击现有轻体思潮的痼疾,以求得我们的体育教育能朝着健康的方向发展.     

试论离婚之精神损害赔偿制度

离婚之精神损害有离因精神损害和离婚精神损害两种.前者是夫妻一方对另一方构成侵权行为而导致离婚,从而给一方造成精神痛苦,受害方可请求精神损害赔偿.我国新的<婚姻法>确立了这一精神损害赔偿制度,填补了我国婚姻制度的一个空缺.而后者是夫妻一方对另一方并无侵权行为,离婚本身即为构成精神损害之直接原因,如由于第三者插足、婚外恋、夫妻一方被判处徒刑等.这种离婚同样使一方受到精神损害,自然也应得精神损害赔偿.遗憾的是,新的<婚姻法>并未作此规定.因此,要完善我国离婚之精神损害赔偿制度,不仅要使离婚之精神损失赔偿的权利义务主体进一步扩大,把第三者也作为离婚之精神损害赔偿的义务主体,而且还要将离因精神损害赔偿扩大到离婚精神损害赔偿,将因婚外恋、第三者插足、因配偶一方犯罪而被判入狱和其他原因导致离婚的情况作出规定,使精神受害者得到应有的经济救济和补偿.     

真实与想象 ——中国古代易装文化的嬗变与文学表现

20世纪以前世界各国的易装文化都以女扮男装为主流,中国古代易装文化非常丰富,又有不同于欧洲的特点。历史上的妇女易装个案与战争、民族融合及科举制度密切相关。至明清时代,添加了反叛礼教和市民文化的色彩,又有遗民、边缘文人“女性化”心态的作用,加上文学上闺秀传统及才女“文人化”的形成,文学易装题材的创作达到高峰,尤以女作家所创作的叙事作品表现女性意识的崛起和追求个性解放、男女平等的理想,而显得意义深远。
