NLOPTIONS <options>;
The NLOPTIONS statement specifies details about the nonlinear optimization technique that PROC SPP uses to maximize the log-likelihood function for the first-order intensity model. By default, PROC SPP uses the Newton-Raphson with ridging optimization technique. For more information about the NLOPTIONS statement, see the section NLOPTIONS Statement in ChapterĀ 19: Shared Concepts and Topics.
