Multiple Changepoint Detection for Non‐Gaussian Time Series

Journal of Time Series Analysis, Volume 47, Issue 3, Page 465-484, May 2026.
ABSTRACT This article combines methods from existing techniques to identify multiple changepoints in non‐Gaussian autocorrelated time series. A transformation is used to convert a Gaussian series into a non‐Gaussian series, enabling penalized likelihood methods to handle non‐Gaussian scenarios.

Comparison of process capability indices under autocorrelated data

, 2007
Summary: The process capability indices provide a measure of how a process fits within the specification limits. In calculating indices is usual to assume that the process data are independent. However, in industrial applications data are often autocorrelated.

Nonparametric Detection of a Time‐Varying Mean

Journal of Time Series Analysis, Volume 47, Issue 3, Page 597-611, May 2026.
ABSTRACT We propose a nonparametric portmanteau test for detecting changes in the unconditional mean of a univariate time series which may display either long or short memory. Our approach is designed to have power against, among other things, cases where the mean component of the series displays abrupt level shifts, deterministic trending behaviour ...

ASSESSING THE FINANCIAL RISKS OF DIVERSIFIED COFFEE PRODUCTION SYSTEMS: AN ALTERNATIVE NONNORMAL CDF ESTIMATION APPROACH [PDF]

Recently developed techniques are adapted and combined for the modeling and simulation of crop yields and prices that can be mutually correlated, exhibit heteroskedasticity or autocorrelation, and follow nonnormal probability density functions.

Signatures of Radiation‐Induced Stress and Putative Selection on Immune Targets in Chornobyl Wolves

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Investigating the physiological and evolutionary consequences of contaminant exposure in wild populations is critical for understanding long‐term ecological impacts of anthropogenic change. However, how and why species persist, even thrive, in highly contaminated regions in the absence of humans remains a topic of much debate.
