The VARIANCE group consists of the beta
estimates, their variance-covariance matrix under the user specified sample
design (DESIGN
option), the SRS (Simple Random Sample) variance-covariance matrix, the
idempotent matrix required for hypothesis testing, and the denominator
degrees of freedom. This group is not printed by default, though the statistics
are available for individual printing, either by explicit use of appropriate
keyword(s) on the PRINT
statement or by VARIANCE=DEFAULT or VARIANCE=ALL on the PRINT statement.
The keywords in the VARIANCE group are listed below in default order.
