Description

Modern Methods for Evaluating Your Social Science Data

With recent advances in computing power and the widespread availability of political choice data, such as legislative roll call and public opinion survey data, the empirical estimation of spatial models has never been easier or more popular. Analyzing Spatial Models of Choice and Judgment with R demonstrates how to estimate and interpret spatial models using a variety of methods with the popular, open-source programming language R.

Requiring basic knowledge of R, the book enables researchers to apply the methods to their own data. Also suitable for expert methodologists, it presents the latest methods for modeling the distances between points—not the locations of the points themselves. This distinction has important implications for understanding scaling results, particularly how uncertainty spreads throughout the entire point configuration and how results are identified.

In each chapter, the authors explain the basic theory behind the spatial model, then illustrate the estimation techniques and explore their historical development, and finally discuss the advantages and limitations of the methods. They also demonstrate step by step how to implement each method using R with actual datasets. The R code and datasets are available on the book’s website.

Reviews

"Analyzing Spatial Models of Choice and Judgment with R is the rare R-instructional book that succeeds on three levels. It clearly sets forth the psychological theory underlying its modeling method. It demonstrates how the mathematics used for the modeling provide principles of construction and interpretation consistent with that theory. And, it features very well-presented and sophisticated R code—sophisticated enough to bring novice users of R very far along the path of proficiency and even enough, in some sections, to educate and challenge more advanced users. Students and practitioners interested in this field, or in latent space modeling in general, should consider it essential reading."
