TITLE:

Some Recent Developments On Crossover Designs

ABSTRACT:

Crossover designs have been used in practice for a long period of time and
remain an indispensable tool for a number of applications, including drug
development studies in the pharmaceutical industry. For the last 30 years
attention has also been given to the determination of optimal and efficient
crossover designs under a variety of different models. One of the issues
that has been controversial is how to deal with possible carryover effects.
In this talk, which assumes no prior knowledge of crossover designs, we
will present some recent results on optimal and efficient crossover designs
for a model that allows two types of carryover effects from each treatment.
The results are also compared to those for more traditional models used
with crossover designs.

New results in this talk are based on joint work with Joachim Kunert, some
of which will be reported in an article scheduled to appear in the Journal
of the American Statistical Association.
