page 151 Table 7.1 Regression sums of squares for several models fit to Duncan's occupational prestige data. These sums of squares are the building blocks of incremental F-tests for the main and interaction effects of the independent variables. The following code is used for "terms" in the model: E, education; I, income; T, occupational type.

page 151 Table 7.2 Analysis of variance table, showing incremental F-tests for the terms in Duncan's occupational prestige regression.

NOTE: In order to get the values shown in Table 7.2, you need to use the /METHOD = test() subcommand in the regression command. Instead of running the regressions twice, we have included them with the regressions needed for Table 7.1. Note that the variables included in the /METHOD=test subcommands are not included in the /METHOD=ENTER subcommand, but SPSS includes them in the regression as if they were. Also note that you need to look for the regression sums of squares on the first row of the ANOVA table when you do not use the /METHOD=test subcommand, and on the second line of the Model 2 section of the ANOVA table when the /METHOD=test subcommand is used.
