pfica: Functional Independent Components Analysis Techniques

Performs penalized (and non-penalized) independent component analysis for univariate functional data. Two alternative versions are implemented, both based on the spectral decomposition of the kurtosis operator. Our methods are interfaced with the basis functions provided in the fda package.
