1. If you have access to SPSS, use the ClassPred Tab to produce standard classification output to the file ‘data3.sav’ as indicated in Figure 21 of LG Tutorial 1 (page 16). If you do not have access to SPSS, use the Edit Copy command to copy the standard classification output (shown in Figure 20 on page 16) to the Clipboard and paste it into Excel. Then sort by ‘Modal’.
2. Compute the frequency distribution for the modal assignment class and confirm that it is the same as shown in the Total row in Figure 10 (LG Tutorial 1, page 9). Why does this distribution not match the cluster size proportions as reported in the Profile Output in Figure 15 of LG Tutorial 1 (page 12).
3. Obtain scoring equations for classifying new cases using the file ‘data3.sav’ or the copy of this file ‘data3_copy.sav’ which works with the demo version of LatentGOLD. These equations can be obtained as an output option in Step 1 using LG 5.1 (One-Step Scoring), or by using the Step3 module in LatentGOLD. Hint: See
