Abstract

This dataset example introduces readers to multiple regression. This technique allows researchers to evaluate whether a continuous dependent variable is a linear function of two or more independent variables. The multiple linear regression model is most commonly estimated via ordinary least squares (OLS), and is sometimes called OLS regression. This example describes multiple regression, discusses the assumptions underlying it, and shows how to estimate and interpret multiple regression models. We illustrate multiple regression using a subset of data from the Race Implicit Attitudes Test 2012 (IAT2012). Specifically, we examine the relationship between political ideology and a measure of implicit racism with self-reported attitudes to African Americans. This is an important topic for understanding the psychological and political bases of racial prejudice in America.
