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
<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.
