A Practical Guide to Age-Period-Cohort Analysis


Book Description

Age-Period-Cohort analysis has a wide range of applications, from chronic disease incidence and mortality data in public health and epidemiology, to many social events (birth, death, marriage, etc) in social sciences and demography, and most recently investment, healthcare and pension contribution in economics and finance. Although APC analysis has been studied for the past 40 years and a lot of methods have been developed, the identification problem has been a major hurdle in analyzing APC data, where the regression model has multiple estimators, leading to indetermination of parameters and temporal trends. A Practical Guide to Age-Period Cohort Analysis: The Identification Problem and Beyond provides practitioners a guide to using APC models as well as offers graduate students and researchers an overview of the current methods for APC analysis while clarifying the confusion of the identification problem by explaining why some methods address the problem well while others do not. Features · Gives a comprehensive and in-depth review of models and methods in APC analysis. · Provides an in-depth explanation of the identification problem and statistical approaches to addressing the problem and clarifying the confusion. · Utilizes real data sets to illustrate different data issues that have not been addressed in the literature, including unequal intervals in age and period groups, etc. Contains step-by-step modeling instruction and R programs to demonstrate how to conduct APC analysis and how to conduct prediction for the future Reflects the most recent development in APC modeling and analysis including the intrinsic estimator Wenjiang Fu is a professor of statistics at the University of Houston.

Age-Period-Cohort Analysis


Book Description

This book explores the ways in which statistical models, methods, and research designs can be used to open new possibilities for APC analysis. Within a single, consistent HAPC-GLMM statistical modeling framework, the authors synthesize APC models and methods for three research designs: age-by-time period tables of population rates or proportions, repeated cross-section sample surveys, and accelerated longitudinal panel studies. They show how the empirical application of the models to various problems leads to many fascinating findings on how outcome variables develop along the age, period, and cohort dimensions.

A Life Course Perspective on Health Trajectories and Transitions


Book Description

This open access book examines health trajectories and health transitions at different stages of the life course, including childhood, adulthood and later life. It provides findings that assess the role of biological and social transitions on health status over time. The essays examine a wide range of health issues, including the consequences of military service on body mass index, childhood obesity and cardiovascular health, socio-economic inequalities in preventive health care use, depression and anxiety during the child rearing period, health trajectories and transitions in people with cystic fibrosis and oral health over the life course. The book addresses theoretical, empirical and methodological issues as well as examines different national contexts, which help to identify factors of vulnerability and potential resources that support resilience available for specific groups and/or populations. Health reflects the ability of individuals to adapt to their social environment. This book analyzes health as a dynamic experience. It examines how different aspects of individual health unfold over time as a result of aging but also in relation to changing socioeconomic conditions. It also offers readers potential insights into public policies that affect the health status of a population.




Applied Longitudinal Data Analysis for Epidemiology


Book Description

A practical guide to the most important techniques available for longitudinal data analysis, essential for non-statisticians and researchers.




Applied Longitudinal Data Analysis for Medical Science


Book Description

Essential for non-statisticians and researchers working with longitudinal data from medical studies, this updated new edition discusses the most important techniques available for analysing data of this type. Using non-technical language, the book explores simple methods such as the paired t-test and summary statistics as well as more sophisticated regression-based methods, including mixed model analysis. The emphasis of the discussion lies in the interpretation of the results of these different methods, covering data analysis with continuous, dichotomous, categorical and other outcome variables. Datasets used throughout the book are provided, enabling readers to re-analyse the examples as they make their way through chapters and improve their understanding of the material. Finally, an extensive and practical overview of, and comparison between, different software packages is provided. Readers will be able to use this book as a practical manual in their everyday work without needing a strong background in statistics.




Age, Period and Cohort Effects


Book Description

Age, Period and Cohort Effects: Statistical Analysis and the Identification Problem gives a number of perspectives from top methodologists and applied researchers on the best ways to attempt to answer Age–Period–Cohort related questions about society. Age–Period–Cohort (APC) analysis is a fundamental topic for any quantitative social scientist studying individuals over time. At the same time, it is also one of the most misunderstood and underestimated topics in quantitative methods. As such, this book is key reference material for researchers wanting to know how to deal with APC issues appropriately in their statistical modelling. It deals with the identification problem caused by the co-linearity of the three variables, considers why some currently used methods are problematic and suggests ideas for what applied researchers interested in APC analysis should do. Whilst the perspectives are varied, the book provides a unified view of the subject in a reader-friendly way that will be accessible to social scientists with a moderate level of quantitative understanding, across the social and health sciences.




Recognizing Rural Ministry


Book Description

Rural ministry can be a frustrating endeavor. Traditional metrics of success are misleading and anecdotal, one-size-fits-all approaches which often fall flat in the field. In Recognizing Rural Ministry, Carl Greene uses his research to suggest tools to customize your ministry to your community and effectively engage often-overlooked mission fields. These tools come from data-driven academic research presented through the lens of the author's lived experience as a dairy farmer, rural pastor, hospice chaplain, rural layperson, rural policy advocate, and administrator of a network of churches. The book is intended for rural ministry practitioners who want to use current scholarship to better examine the complexity and diversity of rural contexts. The book engages with the rural ministry impact of cultural phenomena such as the rise of the “Spiritual but Not Religious” (SBNR) phenomenon and “early old age” (EOA) demographics. The text also addresses key theories surrounding rural subcultures, demographic tools available to describe rural communities, and the shaping influence of rural community rituals on religiosity. Intended for pastors, seminarians, college students, and rural laypersons who are passionate about adding to their toolbox of rural ministry assessment.




Cannabis


Book Description

This book demonstrates how culture matters for the understanding of cannabis use. It stems from the growing body of research on how users manoeuvre stigmatisation and celebrate the subcultural status of cannabis amid rapid transformation of the substance and its societal reception. The volume presents international studies that challenge the normalisation thesis and simplified views on patterns of use, as well as the Western bias in social research of cannabis. Chapters in this book map the variability of cannabis cultures and markets on a global scale including digital, regulated and illicit markets in transformation. They study cannabis through stigmatisation, gender, social worlds, symbolic boundaries, subcultures, and identity work. The chapters address diverse themes, such as how Latvian, Polish, Nigerian or Mexican users negotiate mainstream conservative, and sometimes gendered societal reactions to cannabis - and how Nordic users’ identities are played out in more progressive contexts. Chapters also cover cannabis use by older people and small growers’ cultures in the US and the interconnections between the established cultures and their digital augmentation in Australia. Synthetic cannabis use is studied in New Zealand and the many contradictions of contemporary cannabis policies are highlighted throughout. Taken together, this book offers an assortment of studies that provide a descriptive and conceptual snapshot of ongoing transitions of paradoxically stable cannabis cultures. It was originally published as a special issue of Drugs: Education, Prevention and Policy.




A Practical Guide to Ecological Modelling


Book Description

Mathematical modelling is an essential tool in present-day ecological research. Yet for many ecologists it is still problematic to apply modelling in their research. In our experience, the major problem is at the conceptual level: proper understanding of what a model is, how ecological relations can be translated consistently into mathematical equations, how models are solved, steady states calculated and interpreted. Many textbooks jump over these conceptual hurdles to dive into detailed formulations or the mathematics of solution. This book attempts to fill that gap. It introduces essential concepts for mathematical modelling, explains the mathematics behind the methods, and helps readers to implement models and obtain hands-on experience. Throughout the book, emphasis is laid on how to translate ecological questions into interpretable models in a practical way. The book aims to be an introductory textbook at the undergraduate-graduate level, but will also be useful to seduce experienced ecologists into the world of modelling. The range of ecological models treated is wide, from Lotka-Volterra type of principle-seeking models to environmental or ecosystem models, and including matrix models, lattice models and sequential decision models. All chapters contain a concise introduction into the theory, worked-out examples and exercises. All examples are implemented in the open-source package R, thus taking away problems of software availability for use of the book. All code used in the book is available on a dedicated website.
