iccTraj (version 1.0.4)

Estimates the Intraclass Correlation Coefficient for Trajectory Data

Description

Estimates the intraclass correlation coefficient for trajectory data using a matrix of distances between trajectories. The distances implemented are the extended Hausdorff distances (Min et al. 2007) and the discrete Fréchet distance (Magdy et al. 2015) .
