Multivariate intrinsic local polynomial regression on isometric Riemannian manifolds. Applications to symmetric positive data

IntroductionWe extend intrinsic local polynomial regression (ILPR) to multivariate covariates on arbitrary Riemannian manifolds, providing a general framework to study the action of isometric maps on manifold-valued regression estimators.MethodsWe derive a closed-form expression for the ILPR estimat...
