Subject: lmer and a response that is a proportion
Greetings all,
I am using lmer (lme4 package) to analyze data where the response is a
proportion (0 to 1). It appears to work, but I am wondering if the analysis
is treating the response appropriately - i.e. can lmer do this?
I have used both family=binomial and quasibinomial - is one more appropriate
when the response is a proportion? The coefficient estimates are identical,
but the standard errors are larger with family=binomial.
Thanks very much for any insight you may have!
