Solving BSDE with adaptive control variate. A note on the rate of convergence of the operator P^k
Résumé
This note is a complement of the paper "Solving BSDE with adaptive control variate". It deals with the convergence of the approximating operator P, based on a non parametric regression technique called local averaging. Although the computations are quite standard (see Hardle '92, Gyorfi etal. '02), the specificities of the paper are the following: - the support of the variables is unbounded; - the error has to be measured using specific L2-norms; - errors on the gradient are provided.
