Integrated Environmental Assessment and Management, EarlyView., 2023 Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

General practitioners’ perceptions of asynchronous telemedicine in a randomized controlled trial of teledermatology. [PDF]
, 2004 Background: Telemedicine is viewed as having a key role to play in the Government’s plans to modernise the NHS.1 However, to date there are few studies which have explored the views and acceptability of GPs towards telemedicine in primary care. Aim: To

Distribution-Free Tests of Independence in High Dimensions [PDF]
, 2017 We consider the testing of mutual independence among all entries in a $d$-dimensional random vector based on $n$ independent observations. We study two families of distribution-free test statistics, which include Kendall's tau and Spearman's rho as ...

Interpreting Kendall’s Tau and Tau-U for single-case experimental designs
Cogent Psychology, 2018 Tau (τ), a nonparametric rank order correlation statistic, has been applied to single-case experimental designs with promising results. Tau-U, a family of related coefficients, partitions variance associated with changes in trend and level.

Information Entropy Based on Propagation Feature of Node for Identifying the Influential Nodes
Complexity, 2021 For understanding and controlling spreading in complex networks, identifying the most influential nodes, which can be applied to disease control, viral marketing, air traffic control, and many other fields, is of great importance. By taking the effect of

Dependence Modeling, 2019 We study nonparametric estimators of conditional Kendall’s tau, a measure of concordance between two random variables given some covariates. We prove non-asymptotic pointwise and uniform bounds, that hold with high probabilities.
