Land Degradation &Development, EarlyView.ABSTRACT Understanding the spatiotemporal dynamics of land use change (LUC), land surface temperature (LST), and vegetation indices is critical for assessing ecological changes and informing sustainable land management. This study investigates the long‐term interrelationships between LUC, LST, and vegetation indices in China's Caohai National Nature ...

Another Marčenko-Pastur law for Kendall’s tau
Electronic Communications in ProbabilityBandeira et al. (2017) show that the eigenvalues of the Kendall correlation matrix of $n$ i.i.d. random vectors in $\mathbb{R}^p$ are asymptotically distributed like $1/3 + (2/3)Y_q$, where $Y_q$ has a Marčenko-Pastur law with parameter $q=\lim(p/n)$ if $p, n\to\infty$ proportionately to one another.

A weighted Kendall's tau statistic
A weighted Kendall's tau statistic ([tau]w) is proposed to measure weighted correlation. It can place more emphasis on items having low rankings than those have high rankings, or vice versa.

Kendall's tau for discrete distributions
This thesis focuses on Kendall's tau as a method for measuring association between two discrete random variables. The first part motivates and defines Kendall's tau, introduces the concepts of concordance, discordance, and copula, and demonstrates ...

River Research and Applications, EarlyView.ABSTRACT The Marias River flows from Glacier National Park through northcentral Montana, and into the Missouri River. Annual flows gradually declined from 1902 to 2024 (~3.2%/decade) and the 1952 Tiber Dam and Lake Elwell reservoir were operated to attenuate peak flows and stabilize downstream flows year‐round.

River, EarlyView.Abstract Estimating suspended sediment concentration (SSC) in river channels is essential for understanding hydro‐sedimentological processes, managing water quality, and conserving aquatic ecosystems. This study evaluated different empirical equations to estimate SSC in the lower Madeira River and analyzed its hydro‐sedimentary dynamics based on MODIS ...
