Nonparametric Statistical Inference for Multivariate Niche Overlap
Jonas Beck, Solomon Harrar
In ecological studies niche overlap is often used to quantify species interaction and dynamics. This paper develops a robust, nonparametric statistical framework for quantifying an…
Wilcoxon-Mann-Whitney Effects for Clustered Data: Informative Cluster Size
Changrui Liu, Solomon W. Harrar
In clustered data setting, informative cluster size has been a focus of recent research. In the nonparametric context, the problem has been considered mainly for testing equality o…
Nonparametric Methods for Complex Multivariate Data: Asymptotics and Small Sample Approximations
Yue Cui, Solomon W. Harrar
Quality of Life (QOL) outcomes are important in the management of chronic illnesses. In studies of efficacies of treatments or intervention modalities, QOL scales multi-dimensional…
Nonparametric Method for Clustered Data in Pre-Post Factorial Design
Solomon W. Harrar, Yue Cui
In repeated measures factorial designs involving clustered units, parametric methods such as linear mixed effects models are used to handle within subject correlations. However, as…
