Abstract
This paper studies the expectile regression with error-in-variables to reduce the data error and describe the overall data distribution. Specifically, the asymptotic normality of the proposed estimator is thoroughly investigated, and an IRWLS algorithm based on orthogonal distance expectile regression (ODER) is proposed to estimate the parameters. Extensive simulation studies and real data applications evaluate our method’s capabilities in reducing the measurement error bias, demonstrating our model’s parameter estimation effectiveness, and its capability in reducing the simulation error compared with linear and quantile regression schemes.
