A New Estimator Based on Likelihood Function for Drift Time of Change in Poisson Rate Parameter [PDF]
Although a control chart can signal an out-of-control state in a process, but it does not always indicate when the process change has begun. Identifying the real time of the change in the process, called the change point, is very important for ...

Change Point Estimation in Panel Data without Boundary Issue
Panel data of our interest consist of a moderate number of panels, while the panels contain a small number of observations. An estimator of common breaks in panel means without a boundary issue for this kind of scenario is proposed.

Sequential change-point detection when unknown parameters are present in the pre-change distribution [PDF]
In the sequential change-point detection literature, most research specifies a required frequency of false alarms at a given pre-change distribution $f_{\theta}$ and tries to minimize the detection delay for every possible post-change distribution $g_ ...

Bootstrap Confidence Intervals for Multiple Change Points Based on Two-Stage Procedures
This paper investigates the construction of confidence intervals for multiple change points in linear regression models. First, we detect multiple change points by performing variable selection on blocks of the input sequence; second, we re-estimate ...

Two-Sample Gradual Change Analysis
We propose two-sample gradual change analysis motivated by gender differences observed in a real data set containing jumping speeds of 432 girls and 364 boys aged 6 to 19 years. Looking at this data set from the point of view of change-point analysis is

Bayesian Framework for Multi-Wave COVID-19 Epidemic Analysis Using Empirical Vaccination Data
The COVID-19 pandemic has highlighted the necessity of advanced modeling inference using the limited data of daily cases. Tracking a long-term epidemic trajectory requires explanatory modeling with more complexities than the one with short-time forecasts,

Change‐point analysis in financial networks [PDF]
A major impact of globalization has been the information flow across the financial markets rendering them vulnerable to financial contagion. Research has focused on network analysis techniques to understand the extent and nature of such information flow. It is now an established fact that a stock market crash in one country can have a serious impact on
