The TCOUNTREG Procedure (Experimental)

Syntax: TCOUNTREG Procedure

The following statements are available in the TCOUNTREG procedure:

PROC TCOUNTREG <options> ;
BOUNDS bound1 < , bound2 …> ;
BY variables ;
CLASS variables ;
FREQ variable ;
ID variable ;
INIT initvalue1 <, initvalue2 …> ;
MODEL dependent = <regressors></ options> ;
NLOPTIONS <options> ;
OUTPUT <OUT=SAS-data-set><output-options> ;
RESTRICT restriction1 <, restriction2 …> ;
WEIGHT variable </options> ;
ZEROMODEL dependent variable $\sim $ <zero-inflated regressors> </options> ;

You can specify only one MODEL statement. 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 specified in the first instance is used.
