Abstract: Nonparametric additive regression with general metric-space-valued predictors and general Hilbertian responses is considered. We estimate the component maps of the additive models by the smooth backfitting method. We present a general asymptotic theory and apply the theory to finite-dimensional Hilbertian predictors and manifold-valued predictors. Those predictors include not only standard Euclidean predictors but also compositional, circular, spherical and shape predictors. Our numerical study shows its wide applications.
