Latent growth curve modeling (LGM)―a special case of confirmatory factor analysis designed to model change over time―is an indispensable and increasingly ubiquitous approach for modeling longitudinal data. This volume introduces LGM techniques to researchers, provides easy-to-follow, didactic examples of several common growth modeling approaches, and highlights recent advancements regarding the treatment of missing data, parameter estimation, and model fit. The book covers the basic linear LGM, and builds from there to describe more complex functional forms (e.g., polynomial latent curves), multivariate latent growth curves used to model simultaneous change in multiple variables, the inclusion of time-varying covariates, predictors of aspects of change, cohort-sequential designs, and multiple-group models. The authors also highlight approaches to dealing with missing data, different estimation methods, and incorporate discussion of model evaluation and comparison within the context of LGM. The models demonstrate how they may be applied to longitudinal data derived from the NICHD Study of Early Child Care and Youth Development (SECCYD)..

Latent Destinies examines the formation of postmodern sensibilities and their relationship to varieties of paranoia that have been seen as widespread in this century. Despite the fact that the Cold War has ended and the threat of nuclear annihilation has been dramatically lessened by most estimates, the paranoia that has characterized the period has not gone away. Indeed, it is as if—as O’Donnell suggests—this paranoia has been internalized, scattered, and reiterated at a multitude of sites: Oklahoma City, Waco, Ruby Ridge, Bosnia, the White House, the United Nations, and numerous other places. O’Donnell argues that paranoia on the broadly cultural level is essentially a narrative process in which history and postmodern identity are negotiated simultaneously. The result is an erasure of historical temporality—the past and future become the all-consuming, self-aware present. To explain and exemplify this, O’Donnell looks at such books and films as Libra, JFK, The Crying of Lot 49, The Truman Show, Reservoir Dogs, Empire of the Senseless, Oswald’s Tale, The Executioner’s Song, Underworld, The Killer Inside Me, and Groundhog Day. Organized around the topics of nationalism, gender, criminality, and construction of history, Latent Destinies establishes cultural paranoia as consonant with our contradictory need for multiplicity and certainty, for openness and secrecy, and for mobility and historical stability. Demonstrating how imaginative works of novels and films can be used to understand the postmodern historical condition, this book will interest students and scholars of American literature and cultural studies, postmodern theory, and film studies.

Drawing on the authors’ extensive research in the analysis of categorical longitudinal data, Latent Markov Models for Longitudinal Data focuses on the formulation of latent Markov models and the practical use of these models. Numerous examples illustrate how latent Markov models are used in economics, education, sociology, and other fields. The R and MATLAB® routines used for the examples are available on the authors’ website. The book provides you with the essential background on latent variable models, particularly the latent class model. It discusses how the Markov chain model and the latent class model represent a useful paradigm for latent Markov models. The authors illustrate the assumptions of the basic version of the latent Markov model and introduce maximum likelihood estimation through the Expectation-Maximization algorithm. They also cover constrained versions of the basic latent Markov model, describe the inclusion of the individual covariates, and address the random effects and multilevel extensions of the model. After covering advanced topics, the book concludes with a discussion on Bayesian inference as an alternative to maximum likelihood inference. As longitudinal data become increasingly relevant in many fields, researchers must rely on specific statistical and econometric models tailored to their application. A complete overview of latent Markov models, this book demonstrates how to use the models in three types of analysis: transition analysis with measurement errors, analyses that consider unobserved heterogeneity, and finding clusters of units and studying the transition between the clusters.

This four-volume Major Work contains texts which explore both the foundations of latent variables and factor analysis, and specific contemporary challenges in the field.   The collection has been designed as a multi-disciplinary resource, with literature drawn from many different areas of study, such as sociology, psychology, education and political science.   In the editor’s introductory essay, a general approach to the meaning and use of latent variables in the social sciences is laid out, the basics of factor analysis and how it works are explained, and the logic that guided the selection of literature included in the collection is elaborated upon.  The combination of these elements makes for a truly comprehensive and user-friendly research tool, invaluable to social scientists across a range of disciplines.   Volume One: The Conceptualization and Operationalization of Variables Volume Two: Applications of Unmeasured Variables Volume Three: Factor Analysis for Latent Variables Volume Four: Advanced Topics  

Catherine Hunter articulates complex questions with utter simplicity, releasing the passion that often lies beneath surfaces of our ordinary lives, and guiding us, through subtle connections on many levels, until we "can hear the city breathe." Latent Heat presents a surprisingly full and lyrical exploration of the lives we live together in this place, the suffering, the confusion, and those evanescent moments that sustain us.

This book introduces multiple-latent variable models by utilizing path diagrams to explain the underlying relationships in the models. This approach helps less mathematically inclined students grasp the underlying relationships between path analysis, factor analysis, and structural equation modeling more easily. A few sections of the book make use of elementary matrix algebra. An appendix on the topic is provided for those who need a review. The author maintains an informal style so as to increase the book's accessibility. Notes at the end of each chapter provide some of the more technical details. The book is not tied to a particular computer program, but special attention is paid to LISREL, EQS, AMOS, and Mx. New in the fourth edition of Latent Variable Models: *a data CD that features the correlation and covariance matrices used in the exercises; *new sections on missing data, non-normality, mediation, factorial invariance, and automating the construction of path diagrams; and *reorganization of chapters 3-7 to enhance the flow of the book and its flexibility for teaching. Intended for advanced students and researchers in the areas of social, educational, clinical, industrial, consumer, personality, and developmental psychology, sociology, political science, and marketing, some prior familiarity with correlation and regression is helpful.

Latent Variable Models and Factor Analysis provides a comprehensive and unified approach to factor analysis and latent variable modeling from a statistical perspective. This book presents a general framework to enable the derivation of the commonly used models, along with updated numerical examples. Nature and interpretation of a latent variable is also introduced along with related techniques for investigating dependency. This book: Provides a unified approach showing how such apparently diverse methods as Latent Class Analysis and Factor Analysis are actually members of the same family. Presents new material on ordered manifest variables, MCMC methods, non-linear models as well as a new chapter on related techniques for investigating dependency. Includes new sections on structural equation models (SEM) and Markov Chain Monte Carlo methods for parameter estimation, along with new illustrative examples. Looks at recent developments on goodness-of-fit test statistics and on non-linear models and models with mixed latent variables, both categorical and continuous. No prior acquaintance with latent variable modelling is pre-supposed but a broad understanding of statistical theory will make it easier to see the approach in its proper perspective. Applied statisticians, psychometricians, medical statisticians, biostatisticians, economists and social science researchers will benefit from this book.
