A Critical Look at Some Analyses of Major League Baseball Salaries

At a data analysis exposition sponsored by the Section on Statistical Graphics of the ASA in 1988, 15 groups of statisticians analyzed the same data about salaries of major league baseball players. By examining what they did, what worked, and what failed, we can begin to learn about the relative strengths and weaknesses of different approaches to analyzing data. The data are rich in difficulties. They require reexpression, contain errors and outliers, and exhibit nonlinear relationships. They thus pose a realistic challenge to the variety of data analysis techniques used. The analysis groups chose a wide range of model-fitting methods, including regression, principal components, factor analysis, time series, and CART. We thus have an effective framework for comparing these approaches so that we can learn more about them. Our examination shows that approaches commonly identified with Exploratory Data Analysis are substantially more effective at revealing the underlying patterns in the data and at building parsimonious, understandable models that fit the data well. We also find that common data displays, when applied carefully, are often sufficient for even complex analyses such as this.     

The Future of Serials Cataloging,CONSER and the ISSN: Conversations from the Field

What does the future hold for the shape of serials to come and for cataloging these and other continuing resources? How should cataloging change to cope with still-unknown types of continuing resources? Will there still be a need for cataloging? For CONSER? For ISSN? How can libraries position themselves to partner with nonlibrary metadata creators in a future linked data environment? Four serials experts discuss these and other questions in a free-ranging conversation about the future of serials cataloging.     

The Cataloging of E-Book Readers: A Service Model-Oriented Approach

Abstract

The popularity of e-book readers has exploded over the past several years, and many libraries have begun purchasing and providing access to these devices for their patrons. A large body of academic literature addresses the popularity of e-book readers and the issues involved with purchasing them and licensing material for them, but there is a relatively slim body of literature regarding the cataloging of e-book readers. At present, there is no uniform approach to cataloging e-book readers and libraries are currently employing a number of different methods. This article will describe the approach to cataloging e-book readers adopted at the Z. Smith Reynolds Library of Wake Forest University, which is based on the local service model for e-readers that takes into account how patrons are expected to use the devices as well as licensing concerns about the use of titles on e-readers. In order to make the devices discoverable for patrons with a minimum of confusion, certain unusual cataloging practices are employed (such as coding e-readers as “realia” but giving them a general material designation (GMD) of “electronic resource”). This article argues that the RDA code should accommodate e-book readers by creating carrier types that accurately describe these devices in a way that patrons can understand.     

1992-2002年中国产业结构的变化——基于列标尺量模型的分析

 摘　　要:为测定国民经济产业结构的变动，本文创建了一个基于投入产出技术的列标尺量模型。它将部门的结构系数变动分为直接产品消耗系数的变动和增加值结构系数的变动。该模型对中国1992-2002年间部门结构变动作了计算分析，主要结论是这一阶段我国经济结构变动中，农业、煤炭采选业、石油加工和天然气开采业、化学工业、金属制品业、交通运输设备制造业、电子及通信设备制造业及商业饮食业的主要影响因素是增加值结构系数的变动，但直接产品消耗系数对其他工业、建筑业、食品制造和烟草加工及其他社会服务业的影响也逐渐显著，列标尺量模型的提出为产业的规划调整提供了有效的参考依据。     

Developing a Freely Accessible/Open Access Resource Management Policy at Duke University Libraries: A Case Study

Abstract

Freely accessible and open access resources present unique challenges for librarians working with electronic resources. Due to the fact that many of these resources lack high-quality metadata or the technical support provided by traditional publishers, making them discoverable and maintaining access over time can be tricky. Creating a policy allows for a systematic approach to the management of freely accessible/open access (OA) resources, alleviating problems surrounding lack of staff time or expertise. Many of these resources are already important parts of collections and will only continue to grow in importance. Freely accessible/OA resources allow for a more diverse representation of content, both by subject and format type, and allow a wider array of authors to have their work appear in library collections. This case study will provide a review of freely accessible/OA policies in other libraries, describe why these resources are important to add to our collections, discuss challenges libraries face with managing these resources, and explain how Duke University Libraries is addressing some of these challenges through the development of a policy.     

GMM Estimation of a Stochastic Volatility Model: A Monte Carlo Study

We examine alternative generalized method of moments procedures for estimation of a stochastic autoregressive volatility model by Monte Carlo methods. We document the existence of a tradeoff between the number of moments, or information, included in estimation and the quality, or precision, of the objective function used for estimation. Furthermore, an approximation to the optimal weighting matrix is used to explore the impact of the weighting matrix for estimation, specification testing, and inference procedures. The results provide guidelines that help achieve desirable small-sample properties in settings characterized by strong conditional heteroscedasticity and correlation among the moments.     

国有企业改革与工资支付结构变革的面板数据分析

本文拟考察在1988-2002年期间国企改革对中国城镇工资支付结构变革的影响、特别是工资决定因素的变化。我们发现对教育的回报在增长,而对工作经验的回报在下降。2002年的数据表明：不断扩大的性别工资差距以及不断增加的非市场因素工资溢价可能均已不再上升。国企改革以及重工业在总体产业结构中比重的不断降低对这些部门职工的工资均已产生影响。我们使用1998-2002年回顾性面板数据提供了关于部门所有制结构、是否是党员以及失业等变量对工资影响的固定效应估计。     

Maximum Likelihood Estimation of a Poisson Parameter in a Model of Equioverlapping Samples:A Simulation Study

In a model of equioverlapping samples maximum likelihood estimation of a Poisson parameter is examined and compared with two linear unbiased estimations by mean squared error. Since a likelihood estimator is not explicitly available in general, a simulation study has been performed and the results are illustrated     

Testing for a Change of the Innovation Distribution in Nonparametric Autoregression: The Sequential Empirical Process Approach

We consider a nonparametric autoregression model under conditional heteroscedasticity with the aim to test whether the innovation distribution changes in time. To this end, we develop an asymptotic expansion for the sequential empirical process of nonparametrically estimated innovations (residuals). We suggest a Kolmogorov–Smirnov statistic based on the difference of the estimated innovation distributions built from the first ?ns?and the last n ? ?ns? residuals, respectively (0 ≤ s ≤ 1). Weak convergence of the underlying stochastic process to a Gaussian process is proved under the null hypothesis of no change point. The result implies that the test is asymptotically distribution‐free. Consistency against fixed alternatives is shown. The small sample performance of the proposed test is investigated in a simulation study and the test is applied to a data example.
