Abstract
Sequential experimental design is the process in which trials or runs are added to a pre-existing set of experiments. There are many considerations regarding the nature of sequential experimentation such as how many runs should be added at a time and when should the experiment be deemed complete? In this presentation, two optimal experimental approaches are discussed; power optimal and D-optimal. Power optimal experiments are those in which the statistical power of a parameter in a linear model is maximized for the next set of experiments chosen. D-optimal experiments are those in which the variance of parameter estimates in a linear model is minimized. Military test and evaluation applications are used as the basis for examples and application of the sequential methods discussed.
