| NLOPTIONS Statement |
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.
