Maximal Autocorrelation Functions in Functional Data Analysis
Giles Hooker, Steven Roberts(Submitted on 17 Jul 2014)
This paper proposes a new factor rotation for the context of functional principal components analysis. This rotation seeks to re-represent a functional subspace in terms of directions of decreasing smoothness as represented by a generalized smoothing metric. The rotation can be implemented simply and we show on two examples that this rotation can improve the interpretability of the leading components.
