We propose a nonparametric method to perform functional principal components analysis for the case of sparse longitudinal data. The method aims at irregularly spaced longitudinal data, where the ...

Complementing our analysis of image contrast and lateral resolution in the functional light-sheet microscopy data (Supplementary Fig. 1), we performed a second analysis to validate that (i ...

One of the ways in which functional data analysis differs from other areas of statistics is in the extent to which data are pre-processed prior to analysis. Functional data are invariably recorded ...
