Sample data.
These options let you determine where sample output is written. It can be added to
the active dataset, written to a new dataset, or saved to an external IBM® SPSS® Statistics data
file. Datasets are available during the current session but are not available in subsequent sessions
unless you explicitly save them as data files. Dataset names must adhere to variable naming rules.
If an external file or new dataset is specified, the sampling output variables and variables in the
active dataset for the selected cases are written.

unless you explicitly save them as data files. Dataset names must adhere to variable naming rules.
If an external file or new dataset is specified, the sampling output variables and variables in the
active dataset for the selected cases are written.
Joint probabilities.
These options let you determine where joint probabilities are written. They are
saved to an external SPSS Statistics data file. Joint probabilities are produced if the PPS WOR,
PPS Brewer, PPS Sampford, or PPS Murthy method is selected and WR estimation is not specified.
PPS Brewer, PPS Sampford, or PPS Murthy method is selected and WR estimation is not specified.
Case selection rules.
If you are constructing your sample one stage at a time, you may want to
save the case selection rules to a text file. They are useful for constructing the subframe for
subsequent stages.
