Adaptive designs for clinical trials

proff. M.Zagoraiou, M.Novelli and R.Frieri

  • Date:

    23 JANUARY
    03 FEBRUARY 2023
     from 10:00 to 13:30
  • Event location: Aula IV, Via Belle Arti 41

  • Type: Cycle 38 - Short courses and seminars

Aims: To introduce the fundamental principles of statistically designed experiments. A variety of modern methods, namely sequential experiments in which the experimenter wishes to make use of the information accrued along the way, will be overviewed, connections between them emphasised and ongoing research challenges introduced.

Learning outcomes: An understanding of the major different mechanisms for data collection via adaptive experimental design, their similarities and differences. An appreciation of the impact of the choice of design on the precision and accuracy of the subsequent statistical modelling and inference. An awareness of the challenges presented to data collection methodologies from modern scientific experiments and studies. Familiarity with some of the practical issues in implementing adaptive designs in comparative experiments.

Final exam: group presentation
