Criminologists are ofren interested in examining interactive effects within a regression context. For example, "holding other relevant factors constant, is the effect of delinquent peers on one's own delinquent conduct the same for males and females?" or "is the effect of a given treatment program comparable between first-time and repeat offenders?" A frequent strategy in examining such interactive effects is to test for the difference between two regression coeficients across independ-1. The points we make in this note about the comparison of regression coefficients are applicable to all regression-type problems that yield maximum likelihood
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
