Change point estimation for the telegraph process observed at discrete timesmath.ST

The telegraph process models a random motion with finite velocity and it is usually proposed as an alternative to diffusion models. The process describes the position of a particle moving on the real line, alternatively with constant velocity $+ v$ or $-v$ . The changes of direction are governed by an homogeneous Poisso…
