ANNALS OF STATISTICS, 44(1), 153–182.
author keywords: Change-point; model mis-specification
TL;DR:
It is found that the limiting regime depends on how quickly the alternatives approach a change-point model, and a family of 'intermediate' limits that can transition, at least qualitatively, to the limits in the two extreme scenarios are unraveled.
