Abstract: Multidimensional functional data are becoming more common in various domains such as climate studies, neuroimaging and chemometrics. We will present a nonparametric covariance function estimator for multidimensional functional data. It is based on an efficient spectral regularizations of an operator associated with a reproducing kernel Hilbert space. We will discuss the corresponding numerical and theoretical results.
