Multiscale Change-Point Inference [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2013
We introduce a new estimator SMUCE (simultaneous multiscale change-point estimator) for the change-point problem in exponential family regression. An unknown step function is estimated by minimizing the number of change-points over the acceptance region ...

Algebraic Change-Point Detection [PDF]

open access: yesApplicable Algebra in Engineering, Communication and Computing, 2009
Elementary techniques from operational calculus, differential algebra, and noncommutative algebra lead to a new approach for change-point detection, which is an important field of investigation in various areas of applied sciences and engineering ...

Heterogeneous Change Point Inference [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2016
We propose HSMUCE (heterogeneous simultaneous multiscale change-point estimator) for the detection of multiple change-points of the signal in a heterogeneous gaussian regression model.

Graph-Based Change-Point Detection [PDF]

open access: yesThe Annals of Statistics, 2014
We consider the testing and estimation of change-points -- locations where the distribution abruptly changes -- in a data sequence. A new approach, based on scan statistics utilizing graphs representing the similarity between observations, is proposed ...

Fréchet change-point detection [PDF]

open access: yesThe Annals of Statistics, 2020
We propose a method to infer the presence and location of change-points in the distribution of a sequence of independent data taking values in a general metric space, where change-points are viewed as locations at which the distribution of the data sequence changes abruptly in terms of either its Fr chet mean or Fr chet variance or both. The proposed

Integrating broad‐scale data to assess demographic and climatic contributions to population change in a declining songbird

open access: yesEcology and Evolution, 2020
Climate variation and trends affect species distribution and abundance across large spatial extents. However, most studies that predict species response to climate are implemented at small spatial scales or are based on occurrence‐environment ...

Changes in Flood Regime of the Upper Yangtze River

open access: yesFrontiers in Earth Science, 2021
River flooding affects more people worldwide than other natural hazards. Thus, analysis of the changes in flood regime caused by global warming and increasing anthropogenic activities will help us make adaptive plans for future flood management.

Univariate Mean Change Point Detection: Penalization, CUSUM and Optimality [PDF]

open access: yes, 2018
The problem of univariate mean change point detection and localization based on a sequence of $n$ independent observations with piecewise constant means has been intensively studied for more than half century, and serves as a blueprint for change point ...

m-Consecutive-k-out-of-n: F Structures with a Single Change Point

open access: yesMathematics, 2020
In the present article, we introduce the m-consecutive-k-out-of-n:F structures with a single change point. The aforementioned system consists of n independent components, of which the first n1 units are identically distributed with common reliability p1,
