WebThe right derivative + ′ of any convex function f defined on an open interval, is an increasing cadlag function. Skorokhod space . The set of all càdlàg functions from E to M is often denoted by D(E; M) (or simply D) and is called Skorokhod space after the Ukrainian mathematician Anatoliy Skorokhod. WebJul 22, 2024 · We show how a certain representation of functions in F_d allows to bound the bracketing entropy of sieves of F_d, and therefore derive rates of convergence in nonparametric function estimation. Specifically, for sieves whose growth is controlled by some rate a_n, we show that the empirical risk minimizer has rate of convergence …
