I've spent the last couple of months trying to find real data (not simulated) of a longitudinal study, but I can't seem to find one. Any topic and time frame is fine, but the dependent variable must be binary, and a few covariables are also desirable. I appreciate any help immensely!
Could this work for you?
It seems that this is indeed a longitudinal study involving several binary variables. Click "pdf only" in the upper right-hand corner to see the paper.
