This package consists in an implementation of a robust approach to solve the problem
of multiple change-point estimation in the mean of a Gaussian AR(1) process.
A robust estimator of the autoregression parameter is proposed and used to build a decorrelated series on which a classical penalized least-square approach is applied.
