COUNTREG Procedure

Syntax: COUNTREG Procedure

The following statements are available in the COUNTREG procedure:

  • PROC COUNTREG <options>;

  • BAYES <options>;

  • BOUNDS bound1 < , bound2 …>;

  • BY variables;

  • CLASS variable <options> …<variable <options>> </global-options>;

  • DISPMODEL dependent-variable tilde <dispersion-related-regressors></option>;

  • FREQ variable;

  • INIT initvalue1 <, initvalue2 …>;

  • MODEL dependent-variable tilde <dispersion-related-regressors></ option>;

  • NLOPTIONS <options>;

  • OUTPUT <OUT=SAS-data-set><output-options>;

  • PERFORMANCE <performance-options>;

  • PRIOR _REGRESSORS |parameter-list ~ distribution ;

  • RESTRICT restriction1 <, restriction2 …>;

  • TEST equation1 <, equation2…> / test-options;

  • SCORE <OUT=SAS-data-set> <output-options>;

  • SHOW options;

  • STORE <OUT=>item-store-name;

  • WEIGHT variable </options>;

  • ZEROMODEL dependent-variable tilde <zero-inflated-regressors> </options>;

  • SPATIALEFFECTS <model-spatial-effect-regressors> </options>;

  • SPATIALDISPEFFECTS <dispersion-spatial-effect-regressors> </options>;

  • SPATIALZEROEFFECTS <zero-inflation-spatial-effect-regressors> </option>;

  • SPATIALID variable;

You can specify multiple MODEL statements. The CLASS statement must precede the MODEL statement. If you include the ZEROMODEL statement, it must appear after the MODEL statement. If you specify more than one FREQ or WEIGHT statement, the variable that is specified in the first instance is used.
