An Animated Functional Data Analysis Interface to Cluster Rapid Lung Function Decline and Enhance Center-Level Care in Cystic Fibrosis

Figure 4

Rate-of-change curves projected and clustered by FPCA phenotypes, animated on dashboard (screenshots). Animation sequence shown for an example center on the interface beginning clockwise with (a) showing scatterplot of smoothed curves prior to clustering in gray; (b) late decliners already clustered (green curve) and initial clustering of middle decliners (yellow curves); (c) early decliners (red); (d) finalized and smoothed phenotypes. Full animation available from link “Center-Level Rate-of-Change Animations” on interface.
