Dear Paul,
thank you for outlining the model formula above, which is really helpful! I have a rich dataset with a mean of 100 repeated observations per individual and reason to suspect that there is actually more than one random change point. Is it possible to add a third slope (b3) and a second random change point (between b2 and b3), and how would one go about it? Particularly, I am not sure how to add a second alpha term.
Thanks!
