David Melamed is a Professor of Sociology and Translational Data Analytics at The Ohio State University. His research interests include the emergence of stratification, cooperation and segregation in dynamical systems, and statistics and methodology. Since 2019 he has been co-Editor of Sociological Methodology. Long Doan is an Associate Professor of Sociology at the University of Maryland, College Park. His research examines how various social psychological processes like identity, intergroup competition, and bias help to explain the emergence and persistence of social stratification. He focuses on inequalities based on sexuality, gender, and race.

"Overall, Applications of Regression for Categorical Outcomes Using R is a well-written and valuable introduction to modeling categorical outcomes for graduate students and practitioners in the social sciences and related disciplines. The book achieves its aims (described using a mountain climbing analogy) to “explain how to choose which peak totackle given an empirical problem, distinguish among truly different options, and equivocate when choices are more preferences than substantive decisions.” (pg. 1) The consistent structure across chapters, focus on conceptual understanding, and guidance on grappling with practical considerations make it a nice text for an applied graduate course or for those seeking to learn (or review) these methods."- Maria Tackett, “Applications of Regression for Categorical Outcomes Using R.” The American Statistician, August 2025.
