Chapter 2 begins by discussing some real-data examples of linear relationships between two variables. The chapter then provides a formal introduction to the simple linear regression model, its interpretation, and the assumptions required for its estimation via ordinary least squares (OLS). This is ...

Let's create a new column that contains the logarithm of per-capita GDP by country/region. Note that because we're dealing with powers of 10 in the GDP column, we'll use the base-10 logarithm rather than the natural logarithm to make interpretation easier....
