Download or read book Combining Panel Data Sets with Attrition and Refreshment Samples written by Keisuke Hirano and published by . This book was released on 1998 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many fields researchers wish to consider statistical models that allow for more complex relationships than can be inferred using only cross-sectional data. Panel or longitudinal data where the same units are observed repeatedly at different points in time can often provide the richer data needed for such models. Although such data allows researchers to identify more complex models than cross-sectional data, missing data problems can be more severe in panels. In particular, even units who respond in initial waves of the panel may drop out in subsequent waves, so that the subsample with complete data for all waves of the panel can be less representative of the population than the original sample. Sometimes, in the hope of mitigating the effects of attrition without losing the advantages of panel data over cross-sections, panel data sets are augmented by replacing units who have dropped out with new units randomly sampled from the original population. Following Ridder (1992), who used these replacement units to test some models for attrition, we call such additional samples refreshment samples. We explore the benefits of these samples for estimating models of attrition. We describe the manner in which the presence of refreshment samples allows the researcher to test various models for attrition in panel data, including models based on the assumption that missing data are missing at random (MAR, Rubin, 1976; Little and Rubin, 1987). The main result in the paper makes precise the extent to which refreshment samples are informative about the attrition process; a class of non-ignorable missing data models can be identified without making strong distributional or functional form assumptions if refreshment samples are available.

This book was released on 2013-01-24 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many economic and social surveys are designed as panel studies, which provide important data for describing social changes and testing causal relations between social phenomena. This textbook shows how to manage, describe, and model these kinds of data. It presents models for continuous and categorical dependent variables, focusing either on the level of these variables at different points in time or on their change over time. It covers fixed and random effects models, models for change scores and event history models. All statistical methods are explained in an application-centered style using research examples from scholarly journals, which can be replicated by the reader through data provided on the accompanying website. As all models are compared to each other, it provides valuable assistance with choosing the right model in applied research. The textbook is directed at master and doctoral students as well as applied researchers in the social sciences, psychology, business administration and economics. Readers should be familiar with linear regression and have a good understanding of ordinary least squares estimation. ​

Download or read book The Oxford Handbook of Polling and Survey Methods written by Lonna Rae Atkeson and published by Oxford University Press. This book was released on 2018-07-25 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methodologies used to study public opinion are now in flux. The primary polling method of the last half-century, the telephone survey, is rapidly becoming obsolete as a data collection method. At the same time, new methods of contacting potential respondents and obtaining their response are appearing, providing a variety of options for scholars and practitioners. Generally speaking, we are moving from a polling world that was largely interviewer driven over the phone and face-to-face to predominantly interviewer driven self-administered poll environments, New methods of data collection, however, must still deal with fundamental questions to polling methodology and total survey error including sampling, selection bias, non-response error, poststratification weighting, and questionnaire design features. The Oxford Handbook on Polling and Survey Methods brings together a unique mixture of academics and practitioners, from various backgrounds, academic disciplines, and experiences. In some sense, this is reflective of the interdisciplinary nature of the polling and survey industry: polls and surveys are widely used in academia, government, and the private sector. Designing, implementing, and analyzing high quality, accurate, and cost-effective polls and surveys requires a combination of skills and methodological perspectives. Despite the well-publicized issues that have cropped up in recent political polling, a great deal is known today about how to collect high quality polling and survey data even in complex and difficult environments. Divided into four main sections, the Handbook draws on the existing research and explores data collection methods. It then addresses data analysis and the methods available for combining polling data with other types of data. The next section covers analytic issues, including the new approaches to studying public opinion (ie social media, the analysis of open-ended questions using text analytic tools, and data imputation). The final section focuses on the presentation of polling results, an area where there is a great deal of innovation. A comprehensive overview of the topic, this volume highlights current polling trends provides ideas for the development of new and better approaches for measuring, modeling, and visualizing public opinion and social behavior.

Download or read book Gulf War Veterans written by Institute of Medicine and published by National Academies Press. This book was released on 1999-08-25 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many individuals, groups, and federal agencies have a strong interest in finding answers to the numerous and complex questions regarding the health of Gulf War veterans. Various types of research and health measurement are needed to address these diverse issues. The Institute of Medicine (IOM) was asked by the Department of Veterans Affairs (VA) and the Department of Defense (DoD) to undertake a study to identify important questions concerning the health of Gulf War veterans and then to design a study to answer those questions. The committee determined that it is of fundamental importance to ask how healthy are Gulf War veterans? Are they as healthy as others? What characteristics are associated with differences between the health of Gulf War veterans and the health of others? To address these questions, it will be necessary to measure not only the health status of those who served in the Gulf War, but also to compare Gulf War veterans with other groups. Further, one must continue to follow these groups through time to determine whether the groups differ in the way their health status is changing. As the committee began to develop a design that would address the fundamental questions identified, it realized that such a study could have important implications for understanding not only the health of Gulf War veterans, but also the health of veterans of other conflicts.

Download or read book Social and Behavioral Research and the Internet written by Marcel Das and published by Routledge. This book was released on 2018-10-24 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highlighting the progress made by researchers in using Web-based surveys for data collection, this timely volume summarizes the experiences of leading behavioral and social scientists from Europe and the US who collected data using the Internet. Some chapters present theory, methodology, design, and implementation, while others focus on best practice examples and/or issues such as data quality and understanding paradata. A number of contributors applied innovative Web-based research methods to the LISS panel of CentERdata collected from over 5,000 Dutch households. Their findings are presented in the book. Some of the data is available on the book website. The book addresses practical issues such as data quality, how to reach difficult target groups, how to design a survey to maximize response, and ethical issues that need to be considered. Innovative applications such as the use of biomarkers and eye-tracking techniques are also explored. Part 1 provides an overview of Internet survey research including its methodologies, strengths, challenges, and best practices. Innovative ways to minimize sources of error are provided along with a review of mixed-mode designs, how to design a scientifically sound longitudinal panel and avoid sampling problems, and address ethical requirements in Web surveys. Part 2 focuses on advanced applications including the impact of visual design on the interpretability of survey questions, the impact survey usability has on respondents’ answers, design features that increase interaction, and how Internet surveys can be effectively used to study sensitive issues. Part 3 addresses data quality, sample selection, measurement and non-response error, and new applications for collecting online data. The issue of underrepresentation of certain groups in Internet research and the measures most effective at reducing it are also addressed. The book concludes with a discussion of the importance of paradata and the Web data collection process in general, followed by chapters with innovative experiments using eye-tracking techniques and biomarker data. This practical book appeals to practitioners from market survey research institutes and researchers in disciplines such as psychology, education, sociology, political science, health studies, marketing, economics, and business who use the Internet for data collection, but is also an ideal supplement for graduate and/or upper level undergraduate courses on (Internet) research methods and/or data collection taught in these fields.

Download or read book Advances in monitoring the economy written by Rene Segers and published by Rozenberg Publishers. This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring involves the collection, analysis and evaluation of information over time. For many professionals, monitoring is a central aspect of their work. For example, policy- makers closely watch the e®ects of their current policies to set the right course for reform. Likewise, physicians monitor the well-being of their patients to adjust their treatments when necessary. In business, n̄ancial investors monitor stock prices and interest rates to optimally time their investments, while marketing managers watch their customers' needs and wants to frame their marketing e®orts. The above examples illustrate that monitoring is crucial in many disciplines to make the right decisions at the right moment. For this reason, there has always been a need for improved monitoring methods. With the advent of increasingly powerful computers and advanced analytical techniques, monitoring systems can nowadays process large amounts of information and have become fully automated where desired. A large body of moni- toring methods originate from academics. Especially during the past four decades, many insights from various ēlds such as economics, statistics, psychometrics and econometrics found their way into everyday monitoring practice. With the overwhelming availability of information in some cases, but also the intrinsic lack of information in other cases, the area is continuously faced with new and highly relevant research challenges. The aim of this thesis is to contribute to the development of new monitoring methods by o®ering potential solutions to some of these challenges. The challenges studied in this thesis arise from all three aspects of monitoring, that is from the collection, the analysis as well as from the evaluation of information.

Download or read book Campaigns and Voters in Developing Democracies written by Noam Lupu and published by University of Michigan Press. This book was released on 2019-02-26 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voting behavior is informed by the experience of advanced democracies, yet the electoral context in developing democracies is significantly different. Civil society is often weak, poverty and inequality high, political parties ephemeral and attachments to them weak, corruption rampant, and clientelism widespread. Voting decisions in developing democracies follow similar logics to those in advanced democracies in that voters base their choices on group affiliation, issue positions, valence considerations, and campaign persuasion. Yet developing democracies differ in the weight citizens assign to these considerations. Where few social identity groups are politically salient and partisan attachments are sparse, voters may place more weight on issue voting. Where issues are largely absent from political discourse, valence considerations and campaign effects play a larger role. Campaigns and Voters in Developing Democracies develops a theoretical framework to specify why voter behavior differs across contexts.

Download or read book Moment Estimation with Attrition written by John M. Abowd and published by . This book was released on 1997 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a method that accommodates missing data in longitudinal datasets of the type usually encountered in economic and social applications. The technique uses various extensions of missing at random' assumptions that we customize for dynamic models. Our method, applicable to longitudinal data on persons or firms, is implemented using the Generalized Method of Moments with reweighting that appropriately corrects for the attrition bias caused by the missing data. We apply the method to the estimation of dynamic labor demand models. The results demonstrate that the correction is extremely important.
