UNIANOVA 1609<br />

UNIANOVA DEP BY A B WITH COV<br />

/PRINT=DESCRIPTIVE, TEST(LMATRIX), PARAMETER<br />

/DESIGN.<br />

• Since the design in the DESIGN subcommand is not specified, the default design is used. In<br />

this case, the design includes the intercept term, the covariate COV, and the full factorial<br />

terms of A and B, which are A, B, and A*B.<br />

• For each combination of levels of A and B, SPSS displays the descriptive statistics of DEP.<br />

• The set of L matrices that generates the sums of squares for testing each effect in the<br />

design is displayed.<br />

• The parameter estimates, their standard errors, t tests, confidence intervals, and the<br />

observed power for each test are displayed.<br />

PLOT Subcommand<br />

PLOT provides a variety of plots useful in checking the assumptions needed in the analysis.<br />

The PLOT subcommand can be specified more than once. All of the plots requested on each<br />

PLOT subcommand are produced.<br />

Use the following keywords on the PLOT subcommand to request plots:<br />

SPREADLEVEL Spread-versus-level plots. Plots of observed cell means versus standard<br />

deviations, and versus variances.<br />

RESIDUALS Observed by predicted by standardized residuals plot. A plot is produced for<br />

each dependent variable. In a univariate analysis, a plot is produced for the<br />

single dependent variable.<br />

PROFILE Line plots of dependent variable means for one-way, two-way, or three-way<br />

crossed factors. The PROFILE keyword must be followed by parentheses<br />

containing a list of one or more factor combinations. All factors specified<br />

(either individual or crossed) must be made up of only valid factors on the<br />

factor list. Factor combinations on the PROFILE keyword may use an asterisk<br />

(*) or the keyword BY to specify crossed factors. A factor cannot occur in a<br />

single factor combination more than once.<br />

The order of factors in a factor combination is important, and there is no<br />

restriction on the order of factors. If a single factor is specified after the<br />

PROFILE keyword, a line plot of estimated means at each level of the factor<br />

is produced. If a two-way crossed factor combination is specified, the output<br />

includes a multiple-line plot of estimated means at each level of the first specified<br />

factor, with a separate line drawn for each level of the second specified<br />

factor. If a three-way crossed factor combination is specified, the output<br />

includes multiple-line plots of estimated means at each level of the first<br />

specified factor, with separate lines for each level of the second factor, and<br />

separate plots for each level of the third factor.
