Robust Mean Change-Point Detecting through Laplace Linear Regression Using EM Algorithm
We proposed a robust mean change-point estimation algorithm in linear regression with the assumption that the errors follow the Laplace distribution. By representing the Laplace distribution as an appropriate scale mixture of normal distribution, we developed the expectation maximization (EM) algori...
