“…There are multiple ways to handle regime changes, such as with time-varying AR, MA, CL, and CLMA terms to reflect parameter changes (Bringmann et al, 2016), while keeping in mind that this makes a model sensitive to noise (Boldea & Hall, 2013;Perron, 2006;Stock & Watson, 2009). As with trends, there is no magic bullet for regime changes, and their existence is often uncertain (Badagián, Kaiser, & Peña, 2015). Our model can account for some regime changes with an occasion effect a t , a time-varying unit effect l t Z i (and covariance c ðxyÞ Z ), and impulse terms c ðyÞ u t , c ðxÞ u t , and c ðxyÞ u t that are free to vary.…”

“…Otherwise, the detected CP divides the dataset into two sub-datasets and the search is iterated, until no more CPs are detected. An issue with the standard BS is that it overestimates the number of CPs [17].…”

“…These proposals can be roughly divided into two classes. One class iteratively searches for one changepoint at a time (Anastasiou & Fryzlewicz, 2019; Badagián et al, 2015; Fryzlewicz, 2014; Olshen et al, 2004; Vostrikova, 1981); the canonical example of this approach is binary segmentation. Another class of proposals simultaneously estimates all changepoints by solving a single optimization problem (Auger & Lawrence, 1989; Fearnhead et al, 2019; Haynes et al, 2017; Hocking et al, 2020; Jackson et al, 2005; Jewell & Witten, 2018; Jewell et al, 2020; Killick et al, 2012; Maidstone et al, 2017; Niu & Zhang, 2012; Tibshirani et al, 2005); examples include 0 segmentation and the fused lasso.…”
