Sampling from a Complex Design
InputSample Weight. If the current sample design is part of a larger sample design, you may have
sample weights from a previousstage of the larger design. Youcan specify a numeric variable
containing these weights in the first stage ofthe current design. Sample weights are computed
automatically for subsequent stages of the current design.

Note: The source variable list has the same content across steps of the Wizard. In other words,
variables removed fromthe source list in a particular step are removed from the list in all steps.
Variablesreturned to the source list appear in the list in all steps.
