Risk estimate forn ewspapersubscription by response, controlling for income categor y
Relative risk estimates are computed separatelyfor each income category. Note that the relative
riskof a positive response for newspaper subscribers appears to gradually decrease with increasing
income, which indicates thatyou may be able to further target the mailings.
Summary
Using Complex Samples Crosstabs risk estimates, you found that you can increase your response
rate to direct mailingsby targeting newspaper subscribers. Further,you found some evidence that
the risk estimates may not be constant across Income category,soyoumaybeabletoincrease
your response rate even more by targetinglower-income newspaper subscribers.
Related Procedures
The Complex Samples Crosstabs procedureis a useful tool for obtaining descriptive statistics
of the crosstabulation of categoricalvariables for observations obtained via a complex sampling
design.
The Complex Samples Sampling Wizard is used to specify complex sampling design
specifications andobtain a sample. The sampling plan file created by the Sampling Wizard
contains a default analysisplan and can be specified in the Plan dialog box when you are
analyzing the sample obtainedaccording to that plan.
The Complex Samples Analysis Preparation Wizardis used to set analysis specifications for
an existing complex sample. The analysis plan file created by the Sampling Wizard can be
specifiedin the Plan dialog box when you are analyzing the sample corresponding to that plan.
The Complex Samples Frequencies procedure providesunivariate descriptive statistics of
categorical variables.
