Let's say I have the following eyes. Each one has values over the course of 24months. Some eyes don't have all the values and some have skipped visit ex: one eye will have 00 and 12 months only.
The question is, how can I find out the average trend of thes values when all the eyes are taken together, regardless of whether they're missing values?
