Not an answer to your Q, but there are problems with this kind of aggregation
if you want to use the aggregate analysis to make inferences about the people.
Notably that the aggregates effects might be different to effects at the level
of individuals. If this might be a problem for you may need to go to different
statistical model (and probably a different package).
