Overview

This vignette demonstrates how to compute and visualize FGDI for subjects with Parkinson's disease.

Load Parkinson Data

data(P_Data)
data(P_data_info)

Assign Labels and Compute FGDI

ID <- c(rep("Case", 21), rep("Control", 42))
fgdi_out <- FGDI(P_Data, ID, PVE_I=0.99)

Visualize an Example Joint
