Chapter 7: Analysis of one-way and two-way tables

In Chapter 7 of the textbook Practical Methods for Design and Analysis of Complex Surveys, testing procedures for one-way and two-way tables are presented. The test statistics include a design-based Wald test statistic and various Rao-Scott adjusted test statistics. These test statistics are constructed to account for the sampling complexities, such as stratification, clustering and weighting, thus providing asymptotically valid testing procedures for complex surveys.

In Training Key 250, a design-based Wald test statistic of independence hypothesis for a two-way table is calculated and compared with an unadjusted Pearson test statistic, thus reproducing the results of Example 7.3. The Occupational Health Care Survey data set is used.
