Revise your program from problem 10.2 to perform a non-oblique rotation and compare the factor loadings with the results from 10.2. Output a data set containing the factor scores. Use PROC PRINT to list out the first 10 observations from this data set (hint: use the data set option 088=10). Compare these scores with a simpler method of taking the mean (or sum) of the variables that contribute to the factor. Correlate these two scores.

Problem 10.2

Run the following program to create the data set PRINCIPAL:

Write the statements necessary to run a factor analysis and produce a scree plot. Looking at this plot, decide how many factors you want to maintain, and add an option to the procedure to extract this many factors and to perform a VARIMAX rotation
