I read up quite a number of resources and I'm still unsure how/if I am applying the lmer correctly for my data.
I'm looking for between-group differences in response rates (controlling for baseline values) for 4 incentive groups (there is a within-subjects factor and a between-subjects factor, and it is the group*round interaction that I am interested in).
My data looks like this:
After reading some of the forums and papers, based on what I understood, I coded it this way:
lmer(response_rate ~ Round + Group + Round*Group + (1|ID), data=data)
Just wanted to check if this makes sense/if this is correct?
Any advice/help would be greatly appreciated. Or if there are any basic resources on this for a beginner in stats would also be great.
Thank you so much! :)
