Ok, from my perspective: 1. There may be persistent quadratic behaviour. 2. That it might not be stable doesn't worry me unduly. 3. An obvious question is whether this is in the literature already and if not why not? 4. Saying that it is inverse gamma is just kicking the can down the road. Why inverse gamma? 5. DO has an explanation for the quadratic. Anyway, I see this thread as a net positive! Maybe not for the model, but definitely for science! Statistics: Posted by Paul — 29 minutes ago
