Scatterplot menu selection

step  To produce a scatterplot matrix of the component scores, from the menus choose:

Graphs
 Scatter...

step  Select Matrix.

step  Click Define.

step  Select REGR factor score 1 for analysis 1 through REGR factor score 3 for analysis 1 as the matrix variables.

step  Click OK.

The first plot in the first row shows the first component on the vertical axis versus the second component on the horizontal axis, and the order of the remaining plots follows from there. The scatterplot matrix shows that the first component has a skewed distribution, which is because Price in thousands is skewed. A principal components extraction using a log-transformed price might give better results. The separation that you see in the third component is explained by the fact that Vehicle type is a binary variable. There appears to be a relationship between the first and third components, due to the fact that there are several expensive automobiles but no "luxury trucks." This problem may be alleviated by using a log-transformed price, but if this does not solve the problem, you may want to split the file on Vehicle type.
