This is a 2 day practical PC-based workshop on Statistical Methods Applied to longitudinal data. In longitudinal studies observations on individuals are measured repeatedly through time. This type of design allows the user to estimate the marginal effect of factors/covariates of interest, as well as to assess changes over time. Longitudinal data require special statistical methods, as observations made on each subject cannot be assumed to be independent, making traditional regression methods inappropriate.

The methodology for analyzing longitudinal data takes the correlation between measurements over time into account.

In this course we will present some of the approaches used in longitudinal data analysis, through work examples covering exploratory analysis, modeling and interpretation of the results.
