Exploratory Factor Analysis with SAS

Exercises

1. Replicate the analyses reported in the chapter with the engineering, SDQ, or GDS data. Specifically:

   1. Examine the factor loading plot prior to rotation (if you examine the factor loading plot for the GDS, it will be a three-dimensional plot that is more complex to interpret) and again after trying various rotation strategies. Which do you think provides the best clarification of the result?
   2. For the GDS data, examine a three-factor solution to see whether it is more sensible than the one-, five-, or eight-factor solutions that are described in the chapter. Do the factors make sense? If so, describe what each latent variable is measuring.
2. Using the identification with academics data downloaded in Chapter 2, conduct ...
