Summary
The summary table reviews your analysis plan. The plan consists of one stage with a design of
one stratification variable and one cluster variable. With-replacement (WR) e stimation is used,
and the plan
is saved to c:\nhis2000_subset.csaplan. You can now use this plan file to process
nhis2000_subset.sav with Complex Samples analysis procedures.
Preparing
for Analysis When Sampling Weights Are Not in the Data File
Aloanoffic
er has a collection of customer records, taken according to a complex design;
however, the sampling weights are not included in the file. This information is contained in
bankloan_cs_noweights.sav. For more information, see the topic Sample Files in Appendix A in
IBM SPSS C
omplex Samples 19. Starting with what she knows about the sampling design, the
officer wants to use the Complex Samples Analysis Preparation Wizard to create an analysis plan
for this data file so that it can be processed by ComplexSamplesanalysisprocedures.
The loan o
fficer knows that the records were selected in two stages, with 15 out of 100 bank
branches selected with equal probability and without replacement in the first stage. One hundred
customers were then selected from each of those banks with equal probability and without
replace
ment in the second stage, and information on the number of customers at each bank is
included in the data file. The first step to creating an analysis p lan is to compute the stagewise
inclusion probabilities and final sampling weights.
Computing Inclusion Probabilities and Sampling Weights
