Risk Estimate by Subpopulation

Risk estimate for newspaper subscription by response, controlling for income category
Relative risk estimates are computed separately for each income category. Note that the relative risk of a positive response for newspaper subscribers appears to gradually decrease with increasing income, which indicates that you 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 mailings by targeting newspaper subscribers. Further, you found some evidence that the risk estimates may not be constant across Income category, so you may be able to increase your response rate even more by targeting
Related Procedures
The Complex Samples Crosstabs procedure is a useful tool for obtaining descriptive statistics of the crosstabulation of categorical variables for observations obtained via a complex sampling design.
The Complex Samples Sampling Wizard is used to specify complex sampling design specifications and obtain a sample. The sampling plan file created by the Sampling Wizard contains a default analysis plan and can be specified in the Plan dialog box when you are analyzing the sample obtained according to that plan.
The Complex Samples Analysis Preparation Wizard is used to set analysis specifications for an existing complex sample. The analysis plan file created by the Sampling Wizard can be specified in the Plan dialog box when you are analyzing the sample corresponding to that plan.
The Complex Samples Frequencies procedure provides univariate descriptive statistics of categorical variables.
