Sampling from a Complex Design
Input Sample Weight. If the current sample design is part of a larger sample design, you may have
sample weights from a previous stage of the larger design. You can specify a numeric variable
containing these weights in the first stage of the current design. Sample weights are computed
automatically for subsequent stages of the current design.
Stage Label. Youcanspecifyanoptionalstringlabelforeachstage.Thisisusedintheoutputto
help identify stagewise information.
Note: The source variable list has the same content across steps of the Wizard. In other words,
variables removed from the source list in a particular step are removed from the list in all steps.
Variables returned to the source list appear in the list in all steps.
