David L. Weakliem - Böcker

Examining the major approaches to hypothesis testing and model selection, this book blends statistical theory with recommendations for practice, illustrated with real-world social science examples. It systematically compares classical (frequentist) and Bayesian approaches, showing how they are applied, exploring ways to reconcile the differences between them, and evaluating key controversies and criticisms. The book also addresses the role of hypothesis testing in the evaluation of theories, the relationship between hypothesis tests and confidence intervals, and the role of prior knowledge in Bayesian estimation and Bayesian hypothesis testing. Two easily calculated alternatives to standard hypothesis tests are discussed in depth: the Akaike information criterion (AIC) and Bayesian information criterion (BIC). The companion website ([ital]www.guilford.com/weakliem-materials[/ital]) supplies data and syntax files for the book's examples.

Is political polarization on the rise? Do various “populist” movements have anything in common? Is the opposition between left and right becoming obsolete and, if so, what might replace it? Many of the most pressing questions about contemporary politics involve public opinion. This incisive sociological introduction considers the formation of opinions as not just a matter of individual responses to external conditions, but as a social process in which people influence and are in turn influenced by others. David L. Weakliem illustrates how changes in economic and social conditions affect public opinion and how the distribution of opinions is shaped by the structure of interaction among people. He applies this approach to discuss topics such as political polarization, long-term trends in public opinion, and the prospects for democracy. Combining theory with up-to-date information on public opinion, the book will be of interest to researchers and students alike in sociology, political science, and communication studies.
