Adaptive designs in dose-ranging clinical trials
Abstract: The overall goal of dose-ranging studies is to
establish the existence, nature and extent of dose effect.
Recently, a great effort has been made to investigate and
develop designs and methods for efficient learning about
dose response and more accurate and faster decision making
on dose selection and improved labeling. The focus is on
adaptive and model-based dose-ranging designs.
In this presentation, I will compare the performance of
the different adaptive designs in learning about and estimating
the dose response relationship. The evaluation of statistical
operational characteristics of these new adaptive designs
has been mainly done through comprehensive simulation studies.
There is a need for new theoretical developments in the
methodology for planning, monitoring and analysis for these
sequential
designs

Sequential nonparametric estimation
Abstract: The talk will start with
a short partial survey of results on sequential nonparametric
procedures. Then it will focus on sequential confidence
regions in location models as well as in nonparametric regression
setup. Also, semiparametric sequential test procedures when
a training sample is available will be covered. Both independent
and dependent observations will be considered. Possibility
of application of a suitable version of bootstrap method
will be also discussed. Theoretical results will be accompanied
by simulation study.

The Shiryaev-Roberts Changepoint Detection Procedure
in Retrospect - Theory and Practice
Abstract: A retrospective view of the Shiryaev-Roberts
procedure is presented, placing it in a historical
context and describing its evolution into a powerful changepoint
detection method.

Quickest detection of the spontaneous appearing effects
- fifty years later
Abstract: We describe the very beginning
(since 1959) of our work with A.N.Kolmogorov on the radiolocation
problems which led us to the formulation and solution of
the different versions of the quickest detection of the
spontaneous appearing effects. A panorama of these results,
their developments with numerous applications in different
fields will be presented.
