On the forecast combination puzzle
Webof forecast combination schemes, forecasters still have little guidance on how to solve the “forecast combination puzzle” (Stock and Watson,2004; Smith and Wallis,2009; Claeskens et al.,2016; Chan and Pauwels,2024) — simple averaging often empirically dominates sophisticated weighting schemes that should (asymptotically) be superior. 3 Webanalysis is extended to the forecast evaluation of competing nested models by Clark and West (2006). In this article, we observe that the same framework is relevant to the …
