Change-point detection in panel data via double CUSUM statistic [PDF]
, 2016 In this paper, we consider the problem of (multiple) change-point detection in panel data. We propose the double CUSUM statistic which utilises the cross-sectional change-point structure by examining the cumulative sums of ordered CUSUMs at each point ...

Detecting A Single Change-point
, 2022 This chapter overviews some of the work on detecting and estimating the location of a single change. We first consider the most common change-point problem, namely that of detecting a change in mean, before looking at extensions to detecting other types of change.

Model-Free Change Point Detection for Mixing Processes
IEEE Open Journal of Control SystemsThis paper considers the change point detection problem under dependent samples. In particular, we provide performance guarantees for the MMD-CUSUM test under exponentially $\alpha$, $\beta$, and fast $\phi$-mixing processes, which significantly expands ...

Real-Time Algorithms for the Detection of Changes in the Variance of Video Content Popularity
IEEE Access, 2020 As video content is responsible for more than 70% of the global IP traffic, related resource allocation approaches, e.g., using content caching, become increasingly important.

Ratio tests for change point detection
, 2008 We propose new tests to detect a change in the mean of a time series. Like many existing tests, the new ones are based on the CUSUM process. Existing CUSUM tests require an estimator of a scale parameter to make them asymptotically distribution free ...

Detecting change-points in extremes [PDF]
Statistics and Its Interface, 2015 Even though most work on change-point estimation focuses on changes in the mean, changes in the variance or in the tail distribution can lead to more extreme events. In this paper, we develop a new method of detecting and estimating the change-points in the tail of multiple time series data.
