Many options that are available in SAS/OR PROC NLP can be specified for the optimization subroutines in PROC CALIS by using the NLOPTIONS statement. The NLOPTIONS statement provides more displayed and file output control on the results of the optimization process, and it permits the same set of termination criteria as in PROC NLP. These are more technical options that you might not need to specify in most cases.

Several statistical procedures support the use of NLOPTIONS statement. The syntax of NLOPTIONS statement is common to all these procedures and can be found in the section NLOPTIONS Statement in Chapter 19, Shared Concepts and Topics.

See the section Use of Optimization Techniques for more information about the use of optimization techniques in PROC CALIS.
