WebJun 25, 2024 · This definition shows that expectile is the minimizer of the expected asymmetric least square loss. Thus, the mean value that minimizes the expected (symmetric) squared loss, is a special case of expectile with \rho =0.5. Given a predictor vector \mathbf {x}, the \rho -expectile of the response y could be calculated as
