"Bayesian Experimental Designs for Discrete Distributions"

Abstract:

Three problems that involve discrete data will be discussed. In the first one, a fixed sample size is to be allocated between two binomial populations. Some A and D-optimality criteria will be suggested and their results will be compared. The formulation of the prior distribution on the population proportions will be discussed along with the relevant literature.

In the second problem we will discuss ways to compute the optimal sample size for a hypothesis test on two proportions. The reasoning, the validity, and the results of the methods will be presented. Finally we shall discuss a misclassification problem in one or more categorical variables using a double sampling scheme. Criteria for optimizing that scheme will be presented.
