Hi all, I wonder if anyone can help. I'm trying to calculate the means from a mixed model analysis using Multcomp My code is glht(lme(response~treatment, random=~1|patient, data=statdata, na.action (na.omit)), linfct=mcp(treatment="Means")) It appears that the "Means" option is not valid for lme models, is this correct? I couldn't find anything in the documentation about this. Thanks in advance for any advice!
