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.
