SUDAAN is a statistical software package commonly used for analyzing complex survey data. One of its key features is the ability to incorporate test statements, which allow users to specify specific hypotheses to be tested within their data analysis. These test statements can be utilized in various ways, such as conducting t-tests, ANOVA, and chi-square tests, among others. By utilizing test statements in SUDAAN, researchers can effectively evaluate the significance of their survey data and draw meaningful conclusions from their analysis. This feature enhances the accuracy and reliability of statistical findings, making SUDAAN a valuable tool for researchers in various fields.
How do I use the test statement in SUDAAN? | SUDAAN FAQ
You can use the test statement to obtain different types of chi-squared
tests. Please see pages 278-279 of the SUDAAN manual for a description of the
tests available in the crosstabs procedure. The last two tables in the
output show the chi-squared tests that are requested on the test
statement. They test the null hypothesis that the variables srsex
and racehpra are not related. The nose option is used
on the proc crosstabs statement to suppress the display of the standard
errors. We have done this to make the output more readable.

The test statement can be used in proc regress to produce
several kinds of Wald tests. Please see page 481 of the SUDAAN manual
for more details. Note that proc rlogist does not seem to have a
test
statement.
