Dat a E dito r with sample results
You can see the sampling results in the Data Editor. Three new variables were saved to the
working file, representing the inclusion probabilities and cumulative sampling weights for the
third stage, plus the final sampling weights. These
new weights take into account the weights
computed during the sampling of the first two stages.
Units with values for these variables were selected to the sample.
Units with system-missing values for these variables were not selected.
The company will now use its resources to obtain survey information for the housing units selected

analysis procedures, using the sampling plan demo.csplan to provide the sampling specifications.
