Change Point Detection in Time Series

A widely adopted approach for change point analysis is to minimize an objective function with a penalty term on the number of change points.

This function is used to find changes in mean for data using the test statistic specfified in the test. stat parameter. The changes are found ...

I am trying to detect some changepoints using R, and the package called changepoint (https://cran.r-project.org/web/packages/changepoint/changepoint.pdf).

One of the key challenges in changepoint analysis is the ability to detect multiple changes within a given time series or sequence.

This post compares a few change point detection method available in R given different time series dynamics and research questions.
