Abstract:The usual mean change-point detecting method based on normal linear regression is not robust to heavy-tailed data with potential outlying points. We propose a robust change-point estimation procedure based on a quantile regression model with asymmetric Laplace error distribution and develop a non-iterative sampling algorithm from a Bayesian perspective. The algorithm can generate independently and identically distributed samples approximately from the posterior distribution of the position of the change-point,… Show more
“…10. In their article entitled "Robust Procedure for Change-Point Estimation Using Quantile Regression Model with Asymmetric Laplace Distribution", Yang [10] creates a noniterative sampling process from a Bayesian perspective and offers a robust changepoint estimation method based on a quantile regression model with an asymmetric Laplace error distribution. After conducting a simulation study to demonstrate the procedure's effectiveness with encouraging results, real data are studied to demonstrate the algorithm's utility in comparison to the traditional change-point detection approach based on normal regression.…”
