%description
Implementation for Kendall functional principal component analysis.
Kendall functional principal component analysis is a robust functional
principal component analysis technique for non-Gaussian
functional/longitudinal data. The crucial function of this package is
KFPCA() and KFPCA_reg(). Moreover, least square estimates of functional
principal component scores are also provided. Refer to Rou Zhong, Shishi
Liu, Haocheng Li, Jingxiao Zhang. (2021) <arXiv:2102.01286>. Rou Zhong,
