To follow along with the handout, copy the file /.../S-Tutorials/DatasetDir/education.dat
into your home directory, then start S-PLUS.
This file contains data about school expenditures for each of the 50
states and the District of Columbia. The variables are school expenditures
in 1970 (SE70), each state's citizens' average income in 1968
(PI68), school age population per capita in 1969 (Y69
), urban population per capita in 1970 (Urban70), and two variables
for the state's location: Region (general) and Locale
(specific). We are interested in exploring the relationships between
SE70 and the other variables.
Read this data set into a data frame and attach to it (data frames are explained in detail in another handout).
