This paper investigates the expectile regression with error-in-variables to reduce data error and describe the overall data distribution. It thoroughly examines the asymptotic normality of the proposed estimator and proposes an IRWLS algorithm based on orthogonal distance expectile regression (ODER) to estimate the parameters. Extensive simulation studies and real data applications evaluate the effectiveness of our method in reducing measurement error bias, and demonstrate its capability in reducing simulation error compared to linear and quantile regression schemes.
