WebOct 27, 2024 · In this paper, we propose an outlier-robust model averaging approach by Mallows-type criterion. The key idea is to develop weight choice criteria by minimising an estimator of the expected prediction error for the function being convex with an unique minimum, and twice differentiable in expectation, rather than the expected squared error. Websquares averaging estimators without the i.i.d. normal assumption. This result allows us to decompose the asymptotic risk into the bias and variance components. Hence, the proposed model averaging criterion can be used to address the trade-oﬀ between bias and variance of forecast combination.
