Abstract:
|
This presentation focuses on multiple dose comparisons with a control for the purpose of identifying at least one dose which is superior to a comparator. An interim analysis can be used to drop dose(s) that are found to be either inferior or having little chance to show a statistically significant superiority to the comparator. We study the type-one error and power of various design configurations and propose a strategy for such an analysis.
