Clustering results of Ferraty & Vieu’s FDA method. This figure shows clusters obtained by Ferraty & Vieu’s FDA clustering method described in the “Functional data clustering algorithm using FPC [4]” section. Only the feature of small ball proportions was used for clustering, resulting in 2 clusters. Cluster 1 (top panel) suggests more fluctuations of Nugent scores over time, and Cluster 2 suggests more stable Nugent scores. However, Cluster 2 (bottom panel) does not differentiate women with stable high Nugent scores (i.e. with BV) versus women with low Nugent scores (i.e. no BV) which clearly are two distinct biological states
