A CUSUM-Based Approach for Condition Monitoring and Fault Diagnosis of Wind Turbines
Energies, 2021 This paper presents a cumulative sum (CUSUM)-based approach for condition monitoring and fault diagnosis of wind turbines (WTs) using SCADA data. The main ideas are to first form a multiple linear regression model using data collected in normal operation

Change-point detection in panel data via double CUSUM statistic [PDF]
Electronic Journal of Statistics, 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 ...

Window-Limited CUSUM for Sequential Change Detection [PDF]
IEEE Transactions on Information Theory, 2022 We study the parametric online changepoint detection problem, where the underlying distribution of the streaming data changes from a known distribution to an alternative that is of a known parametric form but with unknown parameters.
