SOURCE Keyword (SIMPLAN command)

The SOURCE keyword specifies whether associations between inputs with categorical distributions (specified by a contingency table) and parameters for inputs with empirical distributions are automatically calculated from the active dataset or whether they can be taken from a simulation plan file, which is given by 'filespec'. The default is SOURCE=AUTOFIT, which specifies that empirical distributions and contingency tables are calculated from the active dataset.

Specifying TYPE=MANUAL, without the DISTRIBUTION keyword, for an input on the SIMINPUT subcommand indicates that the specifications for the input are to be taken from the simulation plan file that is designated by SOURCE='filespec'. This specification is only valid for the following types of inputs: inputs that are described by an empirical distribution in the plan file; inputs that are described by a categorical distribution and included in a contingency table in the plan file.

The following rules apply to inputs with a categorical distribution and that are included in a contingency table in the plan file:

• When TYPE=MANUAL is specified without the DISTRIBUTION keyword, MULTIWAY=YES must be specified on the CONTINGENCY subcommand.
• You cannot specify TYPE=MANUAL (without the DISTRIBUTION keyword) for a subset of inputs that are included in the contingency table. You must either specify TYPE=MANUAL for all such inputs or for none of them.
