Commonly encountered sources of multiplicities include multiple treatments, multiple endpoints, interim analyses and subgroup analyses. This workshop will cover the most common multiplicity problems in trials designed to compare multiple dose\/treatment arms to a common control arm or to compare two treatment arms with respect to multiple endpoints. We will also cover adaptive multi-arm multi-stage group sequential designs with flexible interim analyses at which ineffective or unsafe arms can be dropped and sample sizes can be re-estimated to ensure a well powered study while strongly controlling the type I error rate at nominal level. Using clinical trial examples, we will demonstrate the use of the industry standard software package East\u00ae to illustrate a variety of multiple comparison procedures, including Dunnett, Bonferroni, Holm, Hochberg, Hommel, Fixed Sequence and Fallback tests, which are commonly used in clinical trials. After introducing these basic methods we will cover gatekeeping methods, which are used to address hierarchical multiplicity problems in more complex settings. We will also demonstrate how to design multi-arm multi-stage group sequential trials with the flexibilities to drop ineffective or unsafe arms and to re-estimate sample sizes at interim looks. The methods will be illustrated with the help of the East software for group sequential and adaptive designs<\/p>\n<p><a name=\"4\"><\/a><strong><span style=\"text-decoration: underline\">Short Course 4: Selective Inference in genomics, and elsewhere<\/span><\/strong><\/p>\n<p><strong>Yoav Benjamini<\/strong>, <em>Dep. of Statistics and Operations Research, Tel Aviv University<\/em><br \/>\n<strong>Saumyadipta Pyne<\/strong>, <em>C R Rao AIMSCS, Hyderabad, India<\/em><\/p>\n<p><span style=\"text-decoration: underline\"><strong>Abstract:<\/strong><\/span> Drawing inference on a selected subset of the parameters,\u00a0a subset that is selected because the parameters within seem interesting after viewing the data, is the domain of selective inference.
