This talk follows up on a presentation given by Helene Muller from QM's School
of Biological and Chemical Sciences at a statistics study group meeting in
January 2009.

The problem is to devise an appropriate analysis for investigating if bumblebees
behave in a consistent way. The dataset consists of N=729 observations which
represent repeated measurements on 81 bees under various experimental conditions.
A modelling strategy for these data is presented, which yields to fitting a nested
linear mixed model to the Box-Cox transformed responses. The results from the
corresponding analysis appear to be very satisfying and allow a classification
of bees into consistent and inconsistent ones. This is joint work with Helene
Muller and Lars Chittka.
