Programming Statements

To define the model, you can use most of the programming statements that are allowed in the SAS DATA step. See the SAS Language Reference: Dictionary for more information. The syntax of programming statements used in PROC SSM is identical to that used in the MODEL procedure (see Chapter 19, The MODEL Procedure ) and the NLMIXED procedure (see Chapter 63, The NLMIXED Procedure (SAS/STAT User's Guide)). There is one more restriction: the data step lagging and differencing functions are not allowed.
