The COUNTREG Procedure

Nonlinear Optimization Options

PROC COUNTREG uses the nonlinear optimization (NLO) subsystem to perform nonlinear optimization tasks. In the PROC COUNTREG statement, you can specify nonlinear optimization options that are then passed to the NLO subsystem. For a list of all the nonlinear optimization options, see ChapterĀ 7: Nonlinear Optimization Methods.
