%description
Clusters longitudinal trajectories over time (can be unequally spaced,
unequal length time series and/or partially overlapping series) on a
common time axis. Performs k-means clustering on a single continuous
variable measured over time, where each mean is defined by a thin plate
spline fit to all points in a cluster. Distance is MSE across trajectory
points to cluster spline. Provides graphs of derived cluster splines,
silhouette plots, and Adjusted Rand Index evaluations of the number of
clusters. Scales well to large data with multicore parallelism available
to speed computation.
