2015/16 session 2015-11-24 seminar

The Applied Biostatistics Association (TABA) invites you to a seminar and dinner:

Topic: Analysing longitudinal data when the visit times are informative

Presenter: Eleanor Pullenayegum (PhD), Scientist, Child Health Evaluative Sciences, Sick Kids Hospital

Abstract: Longitudinal data has become common in applied research, and methods such as mixed models and Generalized Estimating Equations (GEEs) are commonplace in the applied statistician’s toolbox. But what if the timings at which visits occur vary among patients in a way that is potentially informative about the outcome of interest? For example, when analyzing disease trajectories from family practice data, what if sicker patients visit more often? You then run the risk of over-estimating the burden of disease, unless you handle your data carefully. This talk will  highlight settings under which standard methods (mixed models, GEEs) can be expected to work, settings under which they should be used with caution, and alternative approaches to analysis (weighting, outputation, and joint models). These concepts will be illustrated using examples from paediatric rheumatology and oncology.
