SELECTING THE NUMBER OF CHANGE-POINTS IN SEGMENTED LINE REGRESSION.

SELECTING THE NUMBER OF CHANGE-POINTS IN SEGMENTED LINE REGRESSION. Segmented line regression has been used in many applications, and the problem of estimating the number of change-points in segmented line regression has been discussed in Kim et al. (2000). This paper studies asymptotic properties of the number of change-points selected by the permutation procedure of Kim et al. (2000). This procedure is based on a sequential application of likelihood ratio type tests, and controls the over-fitting probability by its design. In this paper we show that, under some conditions, the number of change-points selected by the permutation procedure is consistent. Via simulations, the permutation procedure is compared with such information-based criterior as the Bayesian Information Criterion (BIC), the Akaike Information Criterion (AIC), and Generalized Cross Validation (GCV). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Statistica Sinica Pubmed
