Syntax Rules (CSPLAN command)

General

  • PLAN, PLANVARS, and PRINT are global. Only a single instance of each global subcommand is allowed.
  • Within a subcommand, an error occurs if a keyword or attribute is specified more than once.
  • Equals signs shown in the syntax chart are required.
  • Subcommand names and keywords (for example, PPS_WR) must be spelled in full.
  • In general, empty subcommands (that is, those that have no specifications) generate an error. DESIGN is the only subcommand that can be empty.
  • Any variable names that are specified must be valid IBM® SPSS® Statistics variable names.

Creating a Plan

  • Stages are specified in design blocks. The DESIGN subcommand signals the start of a block. The first block corresponds to stage 1, the second to stage 2, and the third to stage 3. One DESIGN subcommand must be specified per stage.
  • The following subcommands are local and apply to the immediately preceding DESIGN subcommand: METHOD, MOS, SIZE, RATE, STAGEVARS, ESTIMATOR, POPSIZE, and INCLPROB. An error occurs if any of these subcommands appears more than once within a block.
  • Available METHOD and ESTIMATOR options depend on the stage.
  • The following subcommands are honored only if a sample design is requested: METHOD, MOS, SIZE, RATE, and STAGEVARS. An error occurs if any of these subcommands is specified for an analysis design.
  • MOS can be specified in stage 1 only.
  • The following subcommands can be used only if an analysis design is requested: ESTIMATOR, POPSIZE, and INCLPROB. An error occurs if any of these subcommands is specified for a sample design.
  • In general, each variable specified in the design can assume only one role. For example, a weight variable cannot be used as a stratification or cluster variable.

Displaying a Plan

  • If CSPLAN VIEW is used, only the PLAN and PRINT subcommands can be specified.
