Hi everybody,
I'm trying to do an 2-way repeated measures ANOVA with uneven number of subjects in each group (more pre than post measurements). The number of data point is like this:
Pre-group 1 (n=22), Post-group 1 (n = 22),
Pre-group 2 (n=22), Post-group 2 (n=16),
Pre-group 3 (n = 22), Post-group 3 (n = 13),
Pre-group 4 (n = 22), Post-group 4 (n = 18).
I have tried to use the function called rm_anova2 ( ) but it doesn't work.
Does anyone know of a function that is able to perform this kind of analysis?

You can do this with anovan.

What do you mean by variable data within the groups?

Can anovan account for unbalanced data within groups; if you have different sample sizes in each group?
