NLOPTIONS <options> ;

You use the NLOPTIONS statement to control aspects of the optimization system that is used to compute maximum likeihood estimates of the parameters of the three-parameter Weibull distribution with an ANALYZE or PROBPLOT statement, and of the parameters of models for recurrent events data with a MODEL statement. The syntax and options of the NLOPTIONS statement are described in Chapter 19, Shared Concepts and Topics (SAS/STAT User's Guide).
