The following statements are available in the SPATIALREG procedure:
PROC SPATIALREG <options>;
BOUNDS bound1 < , bound2 …>;
BY variables;
CLASS variables;
INIT initvalue1 <, initvalue2 …>;
MODEL dependent = <regressors></ options>;
NLOPTIONS <options>;
OUTPUT <OUT=SAS-data-set><output-options>;
PERFORMANCE options;
RESTRICT restriction1 <, restriction2 …>;
TEST equation1 <, equation2 …></test-options>;
SPATIALEFFECTS <model-spatial-effect-regressors>;
SPATIALID variable;
You can specify more than one MODEL statement, as shown in the section Fitting Multiple Models. The CLASS statement must precede the MODEL statement. If you include the SPATIALEFFECTS statement, it must be paired with and appear after the MODEL statement.
