The Cars Example

Consider Figure 2.1, which displays the data table CarsSmall.jmp. You can open this table by clicking on the correct link in the master journal. This data table consists of six rows, corresponding to specific cars of different types, and six variables from the JMP sample data table Cars.jmp.

Figure 2.1: Data Table CarsSmall.jmp

The first column, Automobile, is an identifier column. Our goal is to predict miles per gallon (MPG) from the other descriptive ...
