NLOPTIONS <options>;
The NLOPTIONS statement specifies details of the nonlinear optimization used by PROC SURVEYPHREG to maximize the log likelihood function. By default, the procedure uses the Newton-Raphson optimization technique. For more information about the NLOPTIONS statement, see the section NLOPTIONS Statement in Chapter 19: Shared Concepts and Topics.
