QLIM Procedure

Syntax: QLIM Procedure

The following statements are available in the QLIM procedure:

  • PROC QLIM <options>;

  • BAYES <options>;

  • BOUNDS bound1 < , bound2 …> ;

  • BY variables;

  • CLASS variables;

  • FREQ variable;

  • ENDOGENOUS variables ~ options;

  • HETERO dependent-variables ~ exogenous-variables / options;

  • INIT initvalue1 < , initvalue2 …> ;

  • MODEL dependent-variable = regressors / options;

  • NLOPTIONS <options>;

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

  • PRIOR parameter-list ~ distribution ;

  • RANDOM regressors < / options> ;

  • RESTRICT restriction1 < , restriction2 …> ;

  • TEST options;

  • WEIGHT variable < / options>;

At least one MODEL statement is required. If more than one MODEL statement is used, the QLIM procedure estimates a system of models. If a FREQ or WEIGHT statement is specified more than once, the variable specified in the first instance is used. Main effects and higher-order terms can be specified in the MODEL statement, as in the GLM procedure and PROBIT procedure in SAS/STAT. If a CLASS statement is used, it must precede the MODEL statement.
