The COMPLEX SAMPLES module is a new feature added to SPSS
(Version 12 only) in 2004. It is accessed from the analysis
menu when it is licensed. A wider range of procedures is
available in version 13.
What does it do?
The software currently includes sample selection (CSSELECT), descriptive statistics
(CSDESCRIPTIVES), tables (CSTABULATE) and ratio estimates.
Version 13 will include regression modelling, including
logistic regression for surveys.
These methods are implemented with standard errors from
Documentation for the survey package:
The manual that comes with the COMPLEX SAMPLES module does
little more than take you through how to run the programs.
More help is available by logging in to
the SPSS technical support pages (use a GUEST login with the
password GUEST if you are not a registered commercial user).
The algorithms used in the survey procedures can be accessed
in the STATISTICS section of the site. A search for COMPLEX
SAMPLES will produce some interesting FAQs.
