Fast symmetric additive covariance smoothing
Jona Cederbaum, Fabian Scheipl, Sonja Greven
We propose a fast bivariate smoothing approach for symmetric surfaces that has a wide range of applications. We show how it can be applied to estimate the covariance function in lo…

Functional Linear Mixed Models for Irregularly or Sparsely Sampled Data
Jona Cederbaum, Marianne Pouplier, Phil Hoole +1
We propose an estimation approach to analyse correlated functional data which are observed on unequal grids or even sparsely. The model we use is a functional linear mixed model, a…
