The data set Harass.dat, included on this book’s Web site, contains data on 343 cases created to replicate the results of a study of sexual harassment by Brooks and Perot (1991). The variables are, in order, Age, Marital Status Feminist Ideology, Frequency of the Behavior, Offensiveness of the behavior, and the dependent variable, whether or not the subjects Reported incidents of sexual harassment For each variable, higher numbers represent more of the property. Technically, this is a problem that might be better approached with what is called logistic regression, because the dependent variable is a dichotomy. However we can get a very close approximation to the optimal solution by using plain old linear multiple regression instead. Use multiple regression to predict whether or not sexual harassment will be reported, based on the variables you have here.
