A workshop based on Interaction Effects in Linear and Generalized Linear Models (Kaufman, 2019), a comprehensive and accessible text providing a unified approach to interpreting interaction effects. The book develops the statistical basis for the general principles of a set of interpretive tools, introduces the ICALC Toolkit for Stata, and offers start-to-finish examples applying ICALC to show how to interpret interaction effects for a variety of different techniques of analysis.

The workshop provides a foundation in the principles of interpretation and training in the use of the ICALC Toolkit for Stata to produce the calculations, tables and graphics needed to help understand and explain your results. Consult the schedule and outline of topics for more details.

Instructor: Robert L. (Bob) Kaufman (PhD, University of Wisconsin, 1981)

Kaufman is professor emeritus of sociology and past Chair of the Departments of Sociology at Temple University and at Ohio State University. Much of his research on applied statistics was motivated by specific substantive problems encountered in his research in the area of social stratification and inequality. But he also has a long-standing interest in the general topic of techniques for testing, interpreting, and presenting quantitative results in an appropriate and intuitive fashion, such as the detection and correction of heteroscedasticity and the interpretation of interaction effects. He has published monographs in the Sage Series Advanced Quantitative Techniques in the Social Sciences (#12) and in Quantitative Applications in the Social Sciences (#172). And his papers on quantitative methods appeared in American Sociological Review, American Journal of Sociology, Sociological Methodology, Sociological Methods and Research, and Social Science Quarterly. He served on the editorial board of Sociological Methods and Research for 15 years and taught graduate-level statistics courses almost every year from 1980 to 2018.

NECESSARY BACKGROUNDProficiency with the use and interpretation of regression analysis (ordinary least squares); an introductory knowledge of interaction effects and of the basics of running Stata. Should also have a reader’s knowledge of common non-linear models such as logistic regression, probit analysis and count models.
