Abstract

Standards are essential to guide both technical and information management in providing access to and delivery of content. Standards development, implementation, and use help the information community meet the needs of its users. The information community grapples with a myriad of methods for providing access to content and capturing transaction level information about access to and use of content. Publishers struggle with ways to manage increased content flow. The author discusses the 2002 revision of the Standard for Library Statistics, NISO Z39.7 (NISO is the National Information Standards Organization, a nonprofit association founded in 1939 and accredited by the American National Standards Institute (ANSI)), and the research and assessment that went into its evolution from a static index of data elements to a Web-based data dictionary embracing U.S. and international metrics for describing and measuring information services and delivery.  相似文献

“Nonparametric” in the title is used to say that observations X 1,…,X n come from an unknown distribution F ∈ ? with ? being the class of all continuous and strictly increasing distribution functions. The problem is to estimate the quantile of a given order q ∈ (0,1) of the distribution F. The class ? of distributions is very large; it is so large that even X nq:n , where nq is an integer, may be very poor estimator of the qth quantile. To assess the performance of estimators no properties based on moments may be used: expected values of estimators should be replaced by their medians, their variances—by some characteristics of concentration of distributions around the median. If an estimator is median-biased for one of distributions, the bias of the estimator may be infinitely large for other distributions. In the note optimal estimators with respect to various criteria of optimality are presented. The pivotal function F(T) of the estimator T is introduced which enables us to apply the classical statistical approach.  相似文献

A survey of business schools was conducted to obtain information about the current state of the teaching of business statistics to students enrolled in M.B.A. degree programs. The survey was undertaken for and presented at a June 1986 conference on “Making Statistics More Effective in Schools of Business,” held at the University of Chicago's Graduate School of Business. Information was elicited concerning both the required statistics sequence and elective statistics courses for M.B.A. students, as well as computer usage in these courses. This article summarizes the information obtained from the survey.  相似文献

“文革”初期,听大人们窃窃地说,街上邻居,蹬三轮车的王老头,平时老实巴交的,被街上红卫兵组织调查了。跑到他原籍,查得真相,原来全国解放以前,王老头在乡下老家担任过伪村长,于是,调查他的人一返回,他当天就被揪出来,成为历史反革命分子,挂上牌子戴高帽子游街,那是最初领略“调查”的意思。那时候坐火车来去匆匆的乘客,很多是担负外调任务的,去外地调查某人的历史。一个时期的特征从乘车人的去向目的就可以看得很清楚,八十年代,乘客中做生意的多起来,改革开放了;现在,出外旅游的多了,生活水平提高了,当然,农民兄弟…  相似文献

In recent years the focus of research in survey sampling has changed to include a number of nontraditional topics such as nonsampling errors. In addition, the availability of data from large-scale sample surveys, along with computers and software to analyze the data, have changed the tools needed by survey sampling statisticians. It has also resulted in a diverse group of secondary data users who wish to learn how to analyze data from a complex survey. Thus it is time to reassess what we should be teaching students about survey sampling. This article brings together a panel of experts on survey sampling and teaching to discuss their views on what should be taught in survey sampling classes and how it should be taught.  相似文献

凡是靠碰运气的好事,似乎都与我无缘。形形色色的彩票、名目繁多的奖券,哪怕中奖率高达10%的末等奖,本人都不曾中得一次。谁知有一天,一位衣冠肃整、佩带胸卡的女士翩然而至,满脸堆笑告知:“恭喜您,先生,您的家庭被荣幸地抽取为城市居民调查户,您是我市150万户城市居民按1‰的比率被抽中的1500户中的一户。”这真是:人在家中坐,“喜”从天上来。千里取一,竟然落在我的头上,不能不说是个奇迹。充当家计调查户几个月,感受颇多,在此愿将所思所想秉陈于诸位。责 任 当我从调查员手中接过装订考究的大账簿时,着实感到了责任…  相似文献

The Horvitz-Thompson estimation theory is applied to snowball sampling and some other sampling procedures using a known or unknown graph structure in the survey population. In particular, simple graph-parameter estimators and variance estimators are obtained which are based on various kinds of partial information about the graph.  相似文献

文章针对典型调查的统计学属性提出质疑,通过典型调查与抽样调查、重点调查的比较,指出典型调查作为认识社会的一种工作方法有其重要作用,但作为一种统计调查的组织形式难以完成统计学所赋予统计调查的使命,而并非统计学的范畴。  相似文献

SURVEY is a computer program that simulates samples drawn from a hypothetical county. We use SURVEY in introductory and advanced sample survey classes to allow students to become involved in all stages of the sampling process, from designing the survey, to analyzing it, to dealing with nonresponse.  相似文献

In this paper, we are concerned with designing surveys for detecting patches of some exploitable resource, such as a shellfish stock. We take as our objective that, if there is one or more circular patches above some specified size, then the probability of detecting at least one patch should be high. We show how the required sampling intensity can be modified in the light of information about the likely number and size of patches. The results are applied to two surveys for detecting exploitable patches of cockles ( Cerastoderma edule ).  相似文献

全面调查因抗干扰性弱、不适应市场经济的运作方式 ,其应用范围已收缩到“规模以上” ,以求确保重点。抽样调查现时正被大力推行 ,但受到“五级政府管理经济的体制原因”、“样本框问题”、“样本代表性问题”和“调查经费不足”等四大金刚的阻遏而陷入困境。为了能“准确及时全面”地收集到政府和社会各界迫切需要的统计资料 ,本文提出一种既能保留全面调查优点、又能绕开“样本框陷井”和“代表性泥淖”的方法 ,即“目录———区域———优选”调查法 ,简称区域调查法。  一、什么是区域调查法区域调查法 ,由面积抽样调查法演变而来。我…  相似文献
