HOW TO ANALYSE REPEATED MEASURES DATA?

There are a number of ways of analysing repeated measures data:

Analysing a summary of the time profile.
Split-plot ANOVA - sometimes this is valid, if certain assumptions are satisfied.
Multivariate ANOVA.

This module describes a recently developed method, Antedependence modelling , which explicitly models the correlation over time, and then adjusts for this in assessing treatment effects.

It should not be seen as superior to the other methods mentioned above, but as an additional technique which may help data understanding.

It is most likely to be useful when there are many (say 8 or more) time points, and we are interested in general development over time, rather than behaviour during particular stages.
