1. Conduct the analyses outlined in this chapter. The initial four-factor model is on the accompanying Web site (www.tzkeith.com) as the file “DAS-II first 1.amw,” and the data are in the file labeled “das 2 cov.xls” or “DAS 2 cov.sav.”

2. The files “DAS 5–8 simulated 6.sav” and “DAS 5–8 simulated 6.xls” include 500 cases of  simulated data for the DAS-II.

a. Conduct the first-order factor analyses from this chapter using the simulated data. Interpret the findings. How do the results compare with those in this chapter (and in Exercise 1)? Would you come to different conclusions following these analyses than we did in the chapter?

b. Note the fit indexes. Which changed the most from the analyses in the chapter? Why do you think this may be?

c. As you examine your analyses, are any other hypotheses or models suggested by the findings? If so, conduct these analyses and interpret the findings.
