658 GLM: Univariate<br />

PRINT Subcommand<br />

for the specified model. The value of n must be between 0 and 1, exclusive.<br />

The default value of alpha is 0.05. This means that the default power calculation<br />

is at the 0.05 level, and the default level of the confidence intervals is 95%,<br />

since ( 1 – 0.05)<br />

× 100 = 95 .<br />

PRINT controls the display of optional output.<br />

• Some PRINT output applies to the entire GLM procedure and is displayed only once.<br />

• Additional output can be obtained on the EMMEANS, PLOT, and SAVE subcommands.<br />

• Some optional output may greatly increase the processing time. Request only the output<br />

you want to see.<br />

• If no PRINT command is specified, default output for a univariate analysis includes a factor<br />

information table and a Univariate Tests table (ANOVA) for all effects in the model.<br />

• If more than one PRINT subcommand is specified, only the last one is in effect.<br />

The following keywords are available for GLM univariate analyses. For information on PRINT<br />

specifications appropriate for other GLM models, see GLM: Multivariate and GLM: Repeated<br />

Measures.<br />

DESCRIPTIVES Basic information about each cell in the design. Observed means,<br />

standard deviations, and counts for the dependent variable in all cells.<br />

The cells are constructed from the highest-order crossing of the<br />

between-subjects factors. For a multivariate model, statistics are given<br />

for each dependent variable. If the number of between-subjects factors<br />

plus the number of split variables exceeds 18, the Descriptive Statistics<br />

table is not printed.<br />

HOMOGENEITY Tests of homogeneity of variance. Levene’s test for equality of variances<br />

for the dependent variable across all level combinations of the<br />

between-subjects factors. If there are no between-subjects factors, this<br />

keyword is not valid. For a multivariate model, tests are displayed for<br />

each dependent variable.<br />

PARAMETER Parameter estimates. Parameter estimates, standard errors, t tests, and<br />

confidence intervals.<br />

η 2<br />

ETASQ Partial eta-squared ( ). This value is an overestimate of the actual<br />

effect size in an F test. It is defined as<br />

partial eta-squared =<br />

------------------------------dfh<br />

× F<br />

dfh × F + dfe<br />

where F is the test statistic and dfh and dfe are its degrees of freedom<br />

and degrees of freedom for error. The keyword EFSIZE can be used in<br />

place of ETASQ.<br />

GEF General estimable function table. This table shows the general form<br />

of the estimable functions.
