Fréchet change-point detection [PDF]
The 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

Change Point Analysis for Kumaraswamy Distribution
Mathematics, 2023 The Kumaraswamy distribution is a common type of bounded distribution, which is widely used in agriculture, hydrology, and other fields. In this paper, we use the methods of the likelihood ratio test, modified information criterion, and Schwarz ...

Assessing seasonal variation and trends in rainfall patterns of Madhya Pradesh, Central India
Journal of Water and Climate Change, 2023 Climate change is a worldwide problem caused by various anthropogenic activities, leading to changes in hydroclimatic variables like temperature, rainfall, riverine flow, and extreme hydrometeorological events.

Dynamical model for social distancing in the U.S. during the COVID-19 epidemic
Computational and Mathematical Biophysics, 2020 Background Social distancing has led to a “flattening of the curve” in many states across the U.S. This is part of a novel, massive, global social experiment which has served to mitigate the COVID-19 pandemic in the absence of a vaccine or effective anti-

Ecology 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
Frontiers 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.

Estimation of Change-Point Models
Journal of Mathematical Sciences, 2022 We consider the testing and estimation of change-points, locations where the distribution abruptly changes, in a sequence of observations. Motivated by this problem, in this contribution we first investigate the extremes of Gaussian fields with trend which then help us give asymptotic p-value approximations of the likelihood ratio statistics from ...
