The running statistics of interest is first extracted using a time window which is slid across the time series, and in each window, the running statistics value is computed. KCP (Kernel Change Point) detection proposed by Arlot et al. (2012) <arXiv:1202.3878> is then implemented to flag the change points on the running statistics (Cabrieto et al., 2018, <doi:10.1016/j.ins.2018.03.010>). Change points are located by minimizing a variance criterion based on the pairwise similarities between running statistics which are computed via the Gaussian kernel. KCP can locate change points for a given k number of change points. To determine the optimal k, the KCP permutation test is first carried out by comparing the variance of the running statistics extracted from the original data to that of permuted data. If this test is significant, then there is sufficient evidence for at least one change point in the data. Model selection is then used to determine the optimal k>0.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("kcpRS")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# one-time r2u setup for Ubuntu (noble)

curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash

# then install

sudo apt install r-cran-kcprs

Fast Ubuntu binaries via r2u (no compilation). Run the setup once per machine.

bspm (used by r2u) also needs make: sudo apt install make

sudo dnf copr enable iucar/cran

sudo dnf install R-CRAN-kcpRS

RPMs from the iucar/cran COPR, rebuilt from CRAN.

sudo zypper install R-kcpRS

RPMs auto-built from CRAN on openSUSE OBS.
