Syntax: COUNTREG Procedure
The COUNTREG procedure is controlled by the following statements:
-
PROC COUNTREG
options ;
-
BOUNDS
bound1 < , bound2 ...>
;
-
BY
variables
;
-
CLASS
variables
;
-
FREQ
variable
;
-
INIT
initvalue1 <, initvalue2 ...>
;
-
MODEL
dependent variable = regressors / options
;
-
NLOPTIONS
options
;
-
OUTPUT
options
;
-
RESTRICT
restriction1 <, restriction2 ...>
;
-
WEIGHT
variable
;
-
ZEROMODEL
dependent variable zero-inflated regressors / options
;
There can only be one MODEL statement. The ZEROMODEL statement, if used, must appear after the MODEL statement, and the CLASS statement must precede the MODEL statement. If a FREQ or WEIGHT statement is specified more than once, the variable specified in the first instance is used.
