Venezuelan Rainfall Data Analysed by Using a Bayesian Space–time Model

We consider a set of data from 80 stations in the Venezuelan state of Guárico consisting of accumulated monthly rainfall in a time span of 16 years. The problem of modelling rainfall accumulated over fixed periods of time and recorded at meteorological stations at different sites is studied by using a model based on the assumption that the data follow a truncated and transformed multivariate normal distribution. The spatial correlation is modelled by using an exponentially decreasing correlation function and an interpolating surface for the means. Missing data and dry periods are handled within a Markov chain Monte Carlo framework using latent variables. We estimate the amount of rainfall as well as the probability of a dry period by using the predictive density of the data. We considered a model based on a full second-degree polynomial over the spatial co-ordinates as well as the first two Fourier harmonics to describe the variability during the year. Predictive inferences on the data show very realistic results, capturing the typical rainfall variability in time and space for that region. Important extensions of the model are also discussed.     

Expressing Estimators of Expected Quality Adjusted Survival as Functions of Nelson-Aalen Estimators

Quality adjusted survival has been increasingly advocated in clinical trials to be assessed as a synthesis of survival and quality of life. We investigate nonparametric estimation of its expectation for a general multistate process with incomplete follow-up data. Upon establishing a representation of expected quality adjusted survival through marginal distributions of a set of defined events, we propose two estimators for expected quality adjusted survival. Expressed as functions of Nelson-Aalen estimators, the two estimators are strongly consistent and asymptotically normal. We derive their asymptotic variances and propose sample-based variance estimates, along with evaluation of asymptotic relative efficiency. Monte Carlo studies show that these estimation procedures perform well for practical sample sizes. We illustrate the methods using data from a national, multicenter AIDS clinical trial.     

论经济学中数学方法的运用

随着经济学的发展,数学方法在经济学中的运用日益广泛.当今,数学方法已在经济学研究方法中占据重要地位,起到了十分重要的作用。我们要辩证地对待数学在经济学研究中所发挥的作用,既不能神化,也不能全盘否定。     

成本管理中成本计算方法的选择

企业成本计算方法有两种:成本核算法和作业成本法。成本核算法如运用不当会导致产品成本信息失真、决策依据失真和成本失控等问题;作业成本法相对来说优点更多,是现代企业成本管理中成本计算方法的最佳选择;扬者二之长,使之共同发挥作用,可以达到更好的效果。     

《文章正宗》"四分法"的文体分类史地位

以总集为代表的中国古代文体分类,其主流是日趋繁复的琐碎细分。真德秀的《文章正宗》"四分法"以合并归类独辟蹊径,化繁为简,引人瞩目。真氏"四分法"融合功用性分类、功能性分类和形态性分类于一体,这虽然有违现代文体分类原则,但与古代文体分类的复杂态势相比显得更加合理。真氏"四分法"已与现代文学分类方法有所契合。

西方身份认同研究述评

身份认同是一个非常难以定义的概念,争议集中于身份认同是＂物＂还是＂过程＂,形成身份认同的关键因素是个体还是社会,身份认同与排斥是什么关系;大众媒体是传播和维持民族认同的工具,种族起源是民族身份认同的重要成份,共同语言和生活方式是身份认同的重要构成;身份认同的调查方法多种多样,普遍使用的是定性方法和定量方法,而定性和定量相结合的方法更为可靠。
