Abstract
The focus of the current seminar will be a (very) brief introduction to longitudinal data and their analysis focusing on regression. To start with we will look at longitudinal data and different designs for collecting such data. We will then look at some empirical observations and why they occur before turning our attention to simple linear regression and why it is generally not appropriate to use it for the analysis of such data. Understanding the above is very important but also a neglected aspect of longitudinal data. We will then, very briefly, introduce two methods for appropriately analysing such data: (i) mixed models and (ii) Generalised Estimating Equations.
