The following statements are available in the HPCOUNTREG procedure. Items within angle brackets (< >) or square brackets ([ ]) are optional.

PROC HPCOUNTREG <options> ;
BOUNDS bound1 [ , bound2 …] ;
BY variables ;
FREQ freq-variable ;
INIT initialization1 < , initialization2 …> ;
MODEL dependent-variable = regressors </ options> ;
OUTPUT <output-options> ;
PERFORMANCE performance-options ;
RESTRICT restriction1 [, restriction2 …] ;
WEIGHT variable </ option> ;
ZEROMODEL dependent-variable $\sim $ zero-inflated-regressors </ options> ;

There can be only one MODEL statement. The ZEROMODEL statement, if used, must appear after the MODEL statement. If a FREQ or WEIGHT statement is specified more than once, the variable specified in the first instance is used.
