Functional K-Centroids Clustering Using Phase and Amplitude Components R package fkcentroids version 0.0.3 Cluster functional data using phase and amplitude components of each function. By weighting phase and amplitude variation differently, clustering results can be obtained from multiple perspectives. Routines for synchronization, functional k-means clustering, and functional k-medians clustering are provided.
