Abstract

This dataset example introduces readers to multiple regression with dummy variables. Multiple regression allows researchers to evaluate whether a continuous dependent variable is a linear function of two or more independent variables. When one (or more) of the independent variables is a categorical variable, the most common method of properly including them in the model is to code them as dummy variables. Dummy variables are dichotomous variables coded as 1 to indicate the presence of some attribute and as 0 to indicate the absence of that attribute. The multiple regression model is most commonly estimated via ordinary least squares (OLS), and is sometimes called OLS regression. This example uses a subset of data from the 2015 Fuel Consumption Report from Natural Resources Canada. It presents ...
