Abstract: The testing of multiple hypotheses is a common aspect of data analysis practice. Recent work on multiple testing has focused on contexts such as high throughput data analysis where many tests are run with potentially complex dependence among test statistics. In this talk, we address the issue of subset dependence, in which the value of the test statistic depends on the assumed nullity of the other hypotheses. When hypotheses are highly dependent on the tested subset, it is impossible to produce a consonant (i.e., completely descriptive) multiple test adaptively by substituting joint tests for nonsignificant elementary (or superset) hypotheses. We discuss several representations of this multiple testing procedure and derive procedures to control familywise error rates for these representations. These representations can also be controlled by alternative error rates, such as false discovery rates and k-familywise error rates. To demonstrate how this representation affects data analytic procedure, we will discuss how adaptive representation improves our understanding of data analysis questions in multiple applications from across UTMB.
