Announcing two courses to be held at the Statistical Services Centre, The University of Reading, in early March. Both will be presented by Professor Dallas Johnson, Kansas State University (USA).

***Analysis of Experimental Designs Commonly used in Medical Research***
3 - 5 March 2003
This course is concerned with the analysis of certain kinds of unbalanced experiments that occur in all phases of clinical trials research. In particular, emphasis is placed on analysing designs in which experiment units (often subjects) are assigned to treatment groups under reasonable types of restrictions. These kinds of experiments include multi-centre studies and/or those that involve repeated measurements on each subject. A correct analysis of such experiments usually involves using mixed models that contain more than one error term or non-traditional assumptions on the error term(s).
During the course participants will learn the advantages and disadvantages of using the GLM and MIXED procedures in SAS when trying to obtain correct analyses of these kinds of messy experiments; you will learn which options are important to use and which can be ignored.
***Design and Analysis of Crossover Experiments using SAS GLM and SAS MIXED Procedures***
6 - 7 March 2003
Crossover designs are special types of repeated measures experiments where the experimental units are given different treatments in different sequences over time. They offer some real advantages over traditional parallel subject designs when comparing different treatments because crossover designs allow each subject to serve as his/her own control. There are, however, certain pitfalls that must be avoided if crossover designs are going to be used effectively.
This course will introduce the important issues associated with crossover experiments, and instruct on how to request appropriate statistical analyses using the SAS GLM and MIXED procedures.
