Functional Principal Component Analysis for Derivatives of Multivariate Curves
Grith, Maria; Härdle, Wolfgang Karl; Kneip, Alois; Wagner, Heiko
We present two methods based on functional principal component analysis (FPCA) for the estimation of smooth derivatives of a sample of random functions, which are observed in a more than one-dimensional domain. We apply ...
