Education of clinical research staff in understanding statistical concepts is an area of importance for pharmaceutical companies. This understanding is needed to help them communicate with statisticians using a common language, in designing clinical trials and interpretation of clinical trial results. Such staff has little time for a one-semester or even a one-week continuing education course in statistics. Faced with this reality, we developed a 3-module course,for a total of 1.5 days, which was taught over a period of one month that addresses the needs of this audience. We describe the format and content of the course and provide references that can serve as a resource for teaching such a course. 相似文献

In this article we review the major areas of remote sensing in the Russian literature for the period 1976 to 1985 that use statistical methods to analyze the observed data. For each of the areas, the problems that have been studied and the statistical techniques that have been used are briefly described 相似文献

ABSTRACTScientific research of all kinds should be guided by statistical thinking: in the design and conduct of the study, in the disciplined exploration and enlightened display of the data, and to avoid statistical pitfalls in the interpretation of the results. However, formal, probability-based statistical inference should play no role in most scientific research, which is inherently exploratory, requiring flexible methods of analysis that inherently risk overfitting. The nature of exploratory work is that data are used to help guide model choice, and under these circumstances, uncertainty cannot be precisely quantified, because of the inevitable model selection bias that results. To be valid, statistical inference should be restricted to situations where the study design and analysis plan are specified prior to data collection. Exploratory data analysis provides the flexibility needed for most other situations, including statistical methods that are regularized, robust, or nonparametric. Of course, no individual statistical analysis should be considered sufficient to establish scientific validity: research requires many sets of data along many lines of evidence, with a watchfulness for systematic error. Replicating and predicting findings in new data and new settings is a stronger way of validating claims than blessing results from an isolated study with statistical inferences. 相似文献

国家统计局从2011年4月对外公布经季节调整的包括GDP的四项统计指标的环比数据,这标志着季节调整和环比增长率测算在我国统计工作实践中已经起步.本文从季节调整的理论研究和实践两个方面对各种季节调整模型、国内外理论研究和各国统计工作实践的差异进行比较分析,发现国内外在研究基础、理论和应用研究比例、研究模型的广度和基础理论研究等理论研究方面以及季节调整的指标范围、环比增长率测算、数据的公布等实际工作方面均存在较大差异.这对我国进一步完善季节调整模型和软件,不断提高环比统计数据质量,以及逐步建立月、季度统计调查制度具有重要意义. 相似文献

60年前,国家统计局的正式成立,标志着新中国政府统计机构正式建成运转。回首60年的历程,统计事业的兴衰与祖国命运紧密联系在一起;而统计科研工作作为整个统计事业的重要组成部分,也在曲折与挑战中不断发展和完善。本文从机构人员、科研活动、科研管理、学会建设和学术期刊等五个方面对政府统计科研工作进行了全面的回顾和梳理。今后统计科研工作仍将致力于统计科学的研究与实践,围绕国家统计局中心工作的同时,充分发挥中国统计学会的桥梁、纽带作用,利用杂志等学术平台,不断加强对全国统计科研工作的组织和管理,为我国统计事业的发展发挥重要作用。 相似文献

Abstract. We study statistical procedures to quantify uncertainty in multivariate climate projections based on several deterministic climate models. We introduce two different assumptions – called constant bias and constant relation respectively – for extrapolating the substantial additive and multiplicative biases present during the control period to the scenario period. There are also strong indications that the biases in the scenario period are different from the extrapolations from the control period. Including such changes in the statistical models leads to an identifiability problem that we solve in a frequentist analysis using a zero sum side condition and in a Bayesian analysis using informative priors. The Bayesian analysis provides estimates of the uncertainty in the parameter estimates and takes this uncertainty into account for the predictive distributions. We illustrate the method by analysing projections of seasonal temperature and precipitation in the Alpine region from five regional climate models in the PRUDENCE project. 相似文献

分享经济作为一种新兴经济,社会各界对其认知存在显著差异,导致有关核算研究及统计实践面临诸如定义、生产范围界定、统计分类、估价和增加值估算等问题。为此,本文立足于理论与实 践的角度,结合各方面研究归纳出分享经济的本质,一种有偿暂时性让渡闲置资源使用权的市场性分享 活动,这种活动在互联网通信技术,尤其是分享平台的助力下,进入了规模化发展阶段。同时,利用SNA的生产观点归纳出分享经济的生产与产出统计范围,并对相关统计分类方法和标准进行了探讨。最后,针对分享经济估价问题提出了有关估算方法。 本文的创新在于提出了分享经济活动的理论边界,明确了分享经济核算研究的主体及统计范围,有助于解决统计实践中产品与行业活动“统不进、分不开”的问题,为完善“三新”统计制度提供了参考依据。 相似文献

Conclusion In this brief and highly selective examination of the adequacy of ISSS, it is suggested that statistical and economic research is essential if we are to ensure that these systems are fit for their intended purposes. It is too readily assumed that the statistical infrastructure is either adequate or, if not, of little significance in dealing with the major problems faced by the world today. This is far from being so and, if the necessary research were carried out, the results could make an invaluable contribution to resolving many of those problems. 相似文献

Statistical methods have the potential of being effectively used by industrial practitioners if they
satisfied two criteria: functionality and usability.
Statistical methods are usually the product of statistical research activities of universities and other
research organizations. Some already satisfy these criteria; however, many do not. The effect is that
potentially relevant methods are not used in practice as often as they could be. In this paper we will
present an approach regarding ‘statistics development,’ in which the end-user is given a central
position, so that the results from statistical research aim to meet the needs and requirements of the practitioner.
Examples of known and new methods will be presented, and we will discuss issues such as education in statistics,
the link with statistical consultancy and publication of methods through various channels. 相似文献

Summary. The instigation of mass screening for breast cancer has, over the last three decades, raised various statistical issues and led to the development of new statistical approaches. Initially, the design of screening trials was the main focus of research but, as the evidence in favour of population-based screening programmes mounts, a variety of other applications have also been identified. These include administrative and quality control tasks, for monitoring routine screening services, as well as epidemiological modelling of incidence and mortality. We review the commonly used methods of cancer screening evaluation, highlight some current issues in breast screening and, using examples from randomized trials and established screening programmes, illustrate the role that statistical science has played in the development of clinical research in this field. 相似文献
