The following statements are available in the COUNTREG procedure:
PROC COUNTREG
<options> ;
BOUNDS
bound1 < , bound2 …> ;
BY
variables ;
CLASS
variables ;
DISPMODEL
dependent variable
<dispersion-related regressors> ;
FREQ
variable ;
INIT
initvalue1 <, initvalue2 …> ;
MODEL
dependent = <regressors></ options> ;
NLOPTIONS
<options> ;
OUTPUT
<OUT=SAS-data-set><output-options> ;
RESTRICT
restriction1 <, restriction2 …> ;
SCORE
DATA=SAS-data-set <OUT=SAS-data-set> <output-options> ;
SHOW
options ;
STORE
<OUT=>item-store-name ;
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 that is specified in the first instance is used.
