CSPLAN 349
The CSPLAN procedure creates a complex sample design or analysis specification that is used
by companion procedures in the Complex Samples Option. The CSSELECT procedure uses
specifications from a plan file when selecting cases from the active file. Analysis procedures
in the Complex Samples Option such as CSDESCRIPTIVES require a plan file in order to
produce summary statistics for a complex sample. You can also use CSPLAN to view sample
or analysis specifications within an existing plan file.
The CSPLAN design specification is used only by procedures in the Complex Samples
Option.
Design Specification. CSPLAN writes a sample or analysis design to a file. A sample design
can be used to extract sampling units from the active file. An analysis design is used to
analyze a complex sample. When a sample design is created the procedure automatically
saves an appropriate analysis design to the plan file. Thus, a plan file created for designing a
sample can be used for both sample selection and analysis.
Both sample and analysis designs can specify stratification, or independent sampling within
nonoverlapping groups, as well as cluster sampling, in which groups of sampling units are
selected. A single or multistage design can be specified with a maximum of three stages.
CSPLAN does not actually execute the plan (that is, it does not extract the sample or analyze
data). To sample cases, use a sample design created by CSPLAN as input to the CSSELECT
procedure. To analyze sample data, use an analysis design created by CSPLAN as input to
Complex Samples procedures such as CSDESCRIPTIVES.
