Sashelp Data Sets

The Sashelp.Vote1980 data set contains US county votes-cast proportions and demographic and geographic characteristics for 3,107 US counties in the 1980 presidential election (Pace and Barry 1997). The six explanatory variables are as follows: the population 18 years of age or older (Pop), the population with 12th-grade or higher education (Edu), the number of owned housing units (Houses), the aggregate income (Income), and scaled longitude and latitude of geographic centroids (Longitude, Latitude). The dependent variable LogVoteRate is the logarithm of the proportion of votes cast divided by the variable Pop. The following steps display information about the data set Sashelp.Vote1980 and create Figure B.19:
