ASYMPTOTIC EXPANSIONS APPLIED TO F-TEST CRITERIA

Using asymptotic expansions of the Kummer hypergeometric function, the sequential. F-test criterion is evaluated asymptotically in terms of the sample size. The continuation region inequalities for the test are inverted and expressed in terms of known test criteria. A rapidly converging algorithm for carrying out the sequential procedure is provided. This makes the F-test easier for the practitioner to use. Almost sure finite termination of the sequential. F-test is asserted by appealing to the continuation inequalities and a heuristic asymptotic expansion of the test criterion. Average stopping times of the sequential procedure for a variety of population means and population number configurations are tabulated. The computer symbolic manipulation program MAPLE was used to derive some formulae.     

多复变空间中的阻抗函数和导纳函数

给出阻抗（导纳）和广义阻抗（广义导纳）的普遍表达式，并根据表达式研究它们的性质。从两个重要性质出发，提出两类特殊的函数（阻抗函数和泛阻抗函数）。它们定义于多复变空间或多维实空间中，以就教于广大读者。

A bayesian test for a two-way contingency table using independence priors

One method of testing for independence in a two-way table is based on the Bayes factor, the ratio of the likelihoods under the independence hypothesis H and the alternative hypothesis H. The main difficulty in this approach is the specification of prior distributions on the composite hypotheses H and H. A new Bayesian test statistic is constructed by using a prior distribution on H that is concentrated about the “independence surface” H. Approximations are proposed which simplify the computation of the test statistic. The values of the Bayes factor are compared with values of statistics proposed by Gunel and Dickey (1974), Good and Crook (1987), and Spiegelhalter and Smith (1982) for a number of two-way tables. This investigation suggests a strong relationship between the new statistic and the p-value.     

论杜甫的边缘焦虑及其影响

边缘焦虑是杜甫人格构成的重要因素。边缘焦虑限制了杜甫对理想自我的设计和追求 ,使其社会生活呈现以官府为中心的显著特征 ;边缘焦虑还培植了杜甫的京城情结 ,促进其诗歌创作与社会现实和国家政治生活紧密关联。     

论汉代人的母亲情结

汉代人对母亲怀有深深的崇敬之情 ,统治者或神化母亲 ,或尊母亲以封号 ,或厚葬母亲 ,民间则为母亲尽孝服丧。汉代人为了维护母亲的形象往往杀死侮辱母亲的人 ,对母亲的话言听计从 ,尽心奉养母亲。统治者所颁行的法令法规促进了母亲情结的深化 ,社会舆论对母亲情结的强化起了推波助澜的作用。     

2岁至3岁儿童语言中复句的发展

2岁至3岁是儿童语言发展的一个关键时期,有着最典型的阶段过渡性。这一阶段的儿童语言中,复句处于初期发展阶段,由无到有,由简单到复杂,几乎出现了所有的类型,各种类型的发展也有不平衡性。复句的迅速发展,反映出儿童认知能力的发展。
