Hi Doug
Your first model can't be right, as AM/PM is clearly a fixed effect: it has
just two levels and you are only interested in making inferences about those
two levels. So you can't have AMPM on the right of the random part of the
model. Try not to think of nesting fixed effects in random
Thanks very much Brian.
