hi all - i'm having trouble using lme to specify a mixed effects
model.
i'm pretty sure this is quite easy for the experienced anova-er, which
i unfortunately am not.
i have a data frame with the following columns:
col 1 : Score1 (this is a continuous numeric measure between 0 and
1)
col 2 :
You are confused. You have not specified a grouping random effect,
so this is not a mixed effect model as it stands.
If this is a homework problem, ask a teacher or classmate for help.
Otherwise, try consulting your local statistician. You do not appear
to understand the concepts of mixed
to be more clear, i'm particularly interested in trying to determine
the effect of Class on Score1, while controlling for the effect
Score2 has on Score1 (and Score2 is correlated with
Class (where Class is an ordered variable with exactly 4 distinct
levels)).
i can perform an ANOVA on Score1 with
3 matches
