@.Purpose
Indicates that the estimated number of excess cases will be computed for each record after a model is fit. The NOEXCESS command is used to remove the %EX variable and end the automatic computation of excess values.

Arguments and Subcommands
TERM #
Modifies the definition of the excess rate for product
additive, product additive excess, and additive models. A value of # for EXCESS TERM is equivalent
to the BACK command: BACK
TERM @.
Remarks
The EXCESS command defines a variable called %EX which stores the estimated number of excess cases for each record. These estimates are recomputed after each model is fit. The number of excess cases is defined as the difference between the estimated total number of cases and the estimated number of background cases. (The definitions of the total and background case estimates are presented in the discussions of the FV and BACK commands.)
