Overview (TCM ANALYSIS command)

The TCM ANALYSIS procedure runs user-defined scenarios for a temporal causal model system, with the data from the active dataset. A scenario is defined by a time series, that is referred to as the root series, and a set of user-defined values for that series over a specified time range. The specified values are then used to generate predictions for the time series that are affected by the root series. The procedure requires a model system file that was created by the TCM MODEL procedure. It is assumed that the active dataset is the same data as was used to create the model system file.

Basic Specification

For column-based data, the basic specification is the MODELSYSTEM subcommand, the SCENARIOPERIOD subcommand and at least one SCENARIO subcommand. For multidimensional data, the basic specification is the MODELSYSTEM subcommand, the SCENARIOPERIOD subcommand and at least one SCENARIO subcommand or SCENARIOGROUP subcommand.

Syntax Rules

  • Multiple SCENARIO subcommands are allowed.
  • Multiple SCENARIOGROUP subcommands are allowed. SCENARIOGROUP subcommands apply only to multidimensional data.
  • Multiple TARGETLIST subcommands are allowed.
  • Each keyword can be specified only once within a subcommand.
  • Empty subcommands are not allowed.
  • Parentheses, equals signs, and slashes that are shown in the syntax chart are required.
  • The command name, subcommand names, and keywords must be spelled in full.

Operations

  • The procedure does not honor the PREDICT command. The TCM ANALYSIS procedure provides an option to specify how far to forecast.

Limitations

  • The SPLIT FILE setting is ignored by this procedure.
  • Case weighting is ignored by this procedure.
