Complex Samples General Linear Model
Covariances of parameter estimates. Displays an estimate of the covariance matrix for the
model coefficients.
Correlationsof parameter estimates. Displays an estimate of the correlation matrix for the
model coefficients.
Designeffect. The ratio of the variance of the estimate to the variance obtained by assuming
that the sample is a simple randomsample. This is a measure of the effect of specifying a
complex design, where values further from 1 indicate greater effects.
Squareroot of design effect. This is a measure of the effect of specifying a complex design,
where values further from 1 indicate greater effects.
Modelfit. Displays R2and root mean squared error statistics.
Populationmeans of dependent variable and covariates. Displays summary information about the
dependent variable, covariates, and factors.
Sample design information. Displays summary information a bout the sample, including the
unweighted count and the population size.

TestStatistic. This group allows you to select the type of statistic usedf ortesting hypotheses. You
can choose between F,adjustedF, chi-square, and adjusted chi-square.
SamplingDegrees of Freedom. This group gives you control over the sampling design degrees of
freedomusedtocomputepvaluesfor all test statistics. If based on the sampling design, the value
is the differencebetween the number of primary sampling units and the number of strata in the
