Linear Mixed Models
Summary Statistics. Produces tables for:
 Descriptive statistics. Displays the sample sizes, means, and standard deviations of
the dependent variable and covariates (if specified). These statistics are displayed
for each distinct level combination of the factors.
 Case Processing Summary. Displays the sorted values of the factors, the repeated
measure variables, the repeated measure subjects, and the random-effects subjects
and their frequencies.
Model Statistics. Produces tables for:
 Parameter estimates. Displays the fixed-effects and random-effects parameter
estimates and their approximate standard errors.
 Tests for covariance parameters. Displays the asymptotic standard errors and Wald
tests for the covariance parameters.
 Correlations of parameter estimates. Displays the asymptotic correlation matrix of
the fixed-effects parameter estimates.
 Covariances of parameter estimates. Displays the asymptotic covariance matrix of
the fixed-effects parameter estimates.
 Covariances of random effects. Displays the estimated covariance matrix of random
effects. This option is available only when at least one random effect is specified.
If a subject variable is specified for a random effect, then the common block is
displayed.
 Covariances of residuals. Displays the estimated residual covariance matrix. This
option is available only when a repeated variable has been specified. If a subject
variable is specified, the common block is displayed.
 Contrast coefficient matrix. This option displays the estimable functions used for
testing the fixed effects and the custom hypotheses.
Confidence interval. This value is used whenever a confidence interval is constructed.
Specify a value greater than or equal to 0 and less than 100. The default value is 95.
