Hello,
I'm new to the list so apologies for posting a basic question. Until the latest update of STATA, I've been able to figure out how to do a repeated-measures analysis without getting this error:
could not determine between-subject error term; use bse() option
Now I'm getting it again and can't figure out how to change the syntax. I'm pretty sure I've read every post in this forum on the bseunit/bse error, as well the user manual, the help menus, and whatever I can find online, and am still stuck.
It's an experiment where each person saw 4 types of stimuli (the category variable), and each type had a number of items. The dataset is too large to paste here, so below are the first two participants. There are different numbers of items in each category, but I didn't think that would matter.
Our research question is whether there is an effect of category. We don't need effects of items, but I put them in the model.
I initially thought it would be:
anova score category item, repeated(category)
but that generates the error. Ditto with adding a bse or bseunit.
Thanks in advance for any advice!
