Finds the most optimal change point(s) in the running statistic time series RunStat
by
looking at their kernel-based pairwise similarities.
kcpa(RunStat, Kmax = 10, wsize = 25)
A matrix comprised of the minimized variance criterion Rmin and the optimal change point location(s) for each k from 1 to Kmax
Dataframe of running statistics with rows corresponding to the windows and the columns corresponding to the variable(s) on which these running statistics were computed.
