Book Synopsis Latent Trait and Latent Class Models by : R. Langeheine
Download or read book Latent Trait and Latent Class Models written by R. Langeheine and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on an international conference held at the Institute for Science Education (IPN) in Kiel in August 1985. The IPN is a national research institute for science education of the Federal Republic of Germany associated with the University of Kiel. The aim of this conference-to treat latent trait and latent class models under comparative points of view as well as under application aspects-was realized in many stimulating contributions and very different ways. We asked the authors of these papers to work out their contributions for publication here, not only because many of the papers present new material, but also because the time is ripe for a comprehen sive volume, working up the widespread literature of the past ten years in this field. We have tried to compile a volume that will be of interest to statistically oriented researchers in a variety of disciplines, including psychology, sociology, education, political science, epidemiology, and the like. Although the chapters assume a reasonably high level of methodo logical sophistication, we hope that the book will find its way into advanced courses in the above fields. We are grateful to the IPN for organizing the conference, to our contributors for their untiring efforts in revising their chapters for publication, and to the staff of Plenum Publishing Corporation for helping to make this book a reality.
Book Synopsis Advances in Latent Class Analysis by : Gregory R. Hancock
Download or read book Advances in Latent Class Analysis written by Gregory R. Hancock and published by IAP. This book was released on 2019-05-01 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is latent class analysis? If you asked that question thirty or forty years ago you would have gotten a different answer than you would today. Closer to its time of inception, latent class analysis was viewed primarily as a categorical data analysis technique, often framed as a factor analysis model where both the measured variable indicators and underlying latent variables are categorical. Today, however, it rests within much broader mixture and diagnostic modeling framework, integrating measured and latent variables that may be categorical and/or continuous, and where latent classes serve to define the subpopulations for whom many aspects of the focal measured and latent variable model may differ. For latent class analysis to take these developmental leaps required contributions that were methodological, certainly, as well as didactic. Among the leaders on both fronts was C. Mitchell “Chan” Dayton, at the University of Maryland, whose work in latent class analysis spanning several decades helped the method to expand and reach its current potential. The current volume in the Center for Integrated Latent Variable Research (CILVR) series reflects the diversity that is latent class analysis today, celebrating work related to, made possible by, and inspired by Chan’s noted contributions, and signaling the even more exciting future yet to come.
Book Synopsis An Introduction to Latent Class Analysis by : Nobuoki Eshima
Download or read book An Introduction to Latent Class Analysis written by Nobuoki Eshima and published by Springer Nature. This book was released on 2022-04-09 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides methods and applications of latent class analysis, and the following topics are taken up in the focus of discussion: basic latent structure models in a framework of generalized linear models, exploratory latent class analysis, latent class analysis with ordered latent classes, a latent class model approach for analyzing learning structures, the latent Markov analysis for longitudinal data, and path analysis with latent class models. The maximum likelihood estimation procedures for latent class models are constructed via the expectation–maximization (EM) algorithm, and along with it, latent profile and latent trait models are also treated. Entropy-based discussions for latent class models are given as advanced approaches, for example, comparison of latent classes in a latent class cluster model, assessing latent class models, path analysis, and so on. In observing human behaviors and responses to various stimuli and test items, it is valid to assume they are dominated by certain factors. This book plays a significant role in introducing latent structure analysis to not only young researchers and students studying behavioral sciences, but also to those investigating other fields of scientific research.

Book Synopsis A Comparison of the Fit of Empirical Data to Two Latent Trait Models by : Leah R. Hutten
Download or read book A Comparison of the Fit of Empirical Data to Two Latent Trait Models written by Leah R. Hutten and published by . This book was released on 1979 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few guidelines exist for selecting from the one and three-parameter logistic latent trait models. This study explored fit of empirical data to these two models in terms of degree of violation of model assumptions. Specifically, unidimensionality, guessing, and equality of item discrimination indices were examined. Additionally, fit statistics were explored for data which varied in both sample size and test length. Chi square statistics were used to compare fit of distributions of observed number-right scores to number right scores predicted from latent trait theory. Using the mean of the conditional distribution of number-right scores for a given ability level as the criterion, the Rasch (one-parameter) model was generally found to be superior in fit to data than the three-parameter model for the five data sets utilized in the study. Fit of data to both models improved as the number of items or persons increased. When short tests were constructed from the data such that item discriminations displayed a broad range, better fit was found for the three-parameter model. Improvement in fit for both models was found for data fulfilling the assumption of unidimensionality. Keywords: Latent trait theory, Cognition, Mathematical models, Psychological tests, Aptitude tests. (SDW).
Book Synopsis The Handbook of Personality Dynamics and Processes by : John F. Rauthmann
Download or read book The Handbook of Personality Dynamics and Processes written by John F. Rauthmann and published by Academic Press. This book was released on 2021-01-20 with total page 1406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Personality Dynamics and Processes is a primer to the basic and most important concepts, theories, methods, empirical findings, and applications of personality dynamics and processes. This book details how personality psychology has evolved from descriptive research to a more explanatory and dynamic science of personality, thus bridging structure- and process-based approaches, and it also reflects personality psychology’s interest in the dynamic organization and interplay of thoughts, feelings, desires, and actions within persons who are always embedded into social, cultural and historic contexts. The Handbook of Personality Dynamics and Processes tackles each topic with a range of methods geared towards assessing and analyzing their dynamic nature, such as ecological momentary sampling of personality manifestations in real-life; dynamic modeling of time-series or longitudinal personality data; network modeling and simulation; and systems-theoretical models of dynamic processes. Ties topics and methods together for a more dynamic understanding of personality Summarizes existing knowledge and insights of personality dynamics and processes Covers a broad compilation of cutting-edge insights Addresses the biophysiological and social mechanisms underlying the expression and effects of personality Examines within-person consistency and variability

Book Synopsis Latent Class and Latent Transition Analysis by : Linda M. Collins
Download or read book Latent Class and Latent Transition Analysis written by Linda M. Collins and published by John Wiley & Sons. This book was released on 2013-05-20 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: A modern, comprehensive treatment of latent class and latent transition analysis for categorical data On a daily basis, researchers in the social, behavioral, and health sciences collect information and fit statistical models to the gathered empirical data with the goal of making significant advances in these fields. In many cases, it can be useful to identify latent, or unobserved, subgroups in a population, where individuals' subgroup membership is inferred from their responses on a set of observed variables. Latent Class and Latent Transition Analysis provides a comprehensive and unified introduction to this topic through one-of-a-kind, step-by-step presentations and coverage of theoretical, technical, and practical issues in categorical latent variable modeling for both cross-sectional and longitudinal data. The book begins with an introduction to latent class and latent transition analysis for categorical data. Subsequent chapters delve into more in-depth material, featuring: A complete treatment of longitudinal latent class models Focused coverage of the conceptual underpinnings of interpretation and evaluationof a latent class solution Use of parameter restrictions and detection of identification problems Advanced topics such as multi-group analysis and the modeling and interpretation of interactions between covariates The authors present the topic in a style that is accessible yet rigorous. Each method is presented with both a theoretical background and the practical information that is useful for any data analyst. Empirical examples showcase the real-world applications of the discussed concepts and models, and each chapter concludes with a "Points to Remember" section that contains a brief summary of key ideas. All of the analyses in the book are performed using Proc LCA and Proc LTA, the authors' own software packages that can be run within the SAS® environment. A related Web site houses information on these freely available programs and the book's data sets, encouraging readers to reproduce the analyses and also try their own variations. Latent Class and Latent Transition Analysis is an excellent book for courses on categorical data analysis and latent variable models at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners in the social, behavioral, and health sciences who conduct latent class and latent transition analysis in their everyday work.

Book Synopsis Psychosocial Risk Factors in the Development, Maintenance and Treatment Outcome of Eating Disorders by : Matteo Aloi
Download or read book Psychosocial Risk Factors in the Development, Maintenance and Treatment Outcome of Eating Disorders written by Matteo Aloi and published by Frontiers Media SA. This book was released on 2024-09-25 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating disorders (EDs) are mental disorders characterized by altered eating habits and excessive concerns about weight and body shape. They arise mainly during adolescence and predominantly affect females. The three most common types of EDs are: •Anorexia nervosa (AN), which is characterized by restriction of food intake, significant low body weight, an intense fear of gaining weight and disturbances in body shape and weight experience; •Bulimia nervosa (BN), which is characterized by recurrent binge-eating episodes followed by behaviors that compensate for the overeating (i.e., self-induced vomiting, excessive exercise, or extreme use of laxatives, enemas or diuretics), and self-evaluation based on body shape and weight; •Binge eating disorder (BED), which is characterized by the recurrence of binge-eating episodes without the use of compensatory behaviors for weight control, and feelings of distress, embarrassment and guilt. To date, researchers and clinicians agree that a multifactorial model is the most suitable for explaining the onset and maintenance of EDs. For example, a risk factor for BED may be lower parental care, as it may trigger greater confusion and uncertainty in responding to unpleasant emotional experiences. This contributes to an impaired personality development, more severe psychopathological symptomatology, and greater difficulty in both identifying and distinguishing feelings of hunger and satiety from other emotions. Attachment styles have also been explored in patients with EDs. According to the attachment theory, attachment insecurity could disrupt the ability to identify and express emotional states and might impair affect regulation skills (i.e. emotional dysregulation). Within the two main dimensions of attachment insecurity (i.e., attachment anxiety and avoidance), higher attachment anxiety is related to greater symptom severity in patients with AN and BN. Moreover, prior studies have examined impaired emotional competences (ECs), theory of mind (ToM) and metacognition, which refer to how individuals identify, express, understand, regulate, and use their emotions or those of significant others. These skills may also explain why attachment insecurity places individuals at greater risk of EDs. Although particular personality traits (i.e. impulsivity, perfectionism, self-esteem), attachment styles, trauma, and metacognition clearly play a role in the onset and maintenance of EDs, little is known about their associations and underlying mechanisms.
Book Synopsis The SAGE Handbook of Quantitative Methodology for the Social Sciences by : David Kaplan
Download or read book The SAGE Handbook of Quantitative Methodology for the Social Sciences written by David Kaplan and published by SAGE. This book was released on 2004-06-21 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative methodology is a highly specialized field, and as with any highly specialized field, working through idiosyncratic language can be very difficult made even more so when concepts are conveyed in the language of mathematics and statistics. The Sage Handbook of Quantitative Methodology for the Social Sciences was conceived as a way of introducing applied statisticians, empirical researchers, and graduate students to the broad array of state-of-the-art quantitative methodologies in the social sciences. The contributing authors of the Handbook were asked to write about their areas of expertise in a way that would convey to the reader the utility of their respective methodologies. Relevance to real-world problems in the social sciences is an essential ingredient of each chapter. The Handbook consists of six sections comprising twenty-five chapters, from topics in scaling and measurement, to advances in statistical modelling methodologies, and finally to broad philosophical themes that transcend many of the quantitative methodologies covered in this handbook.
