Unbiasedness and efficiency of non-parametric and UMVUE estimators of the probabilistic index and related statistics

open access: yesStatistical Methods in Medical Research, 2020
In reliability theory, diagnostic accuracy, and clinical trials, the quantity P ( X > Y ) + 1 / 2 P ( X = Y ) , also known as the Probabilistic Index (PI), is a common treatment effect measure when comparing two groups of observations. The quantity P ( X

Cluster permutation analysis for EEG series based on non-parametric Wilcoxon–Mann–Whitney statistical tests

open access: yesSoftwareX, 2022
Cluster-based permutation tests are widely used in neuroscience studies for the analysis of high-dimensional electroencephalography (EEG) and event-related potential (ERP) data as it may address the multiple comparison problem without reducing the ...

A Novel Non-Parametric Spatiotemporal Scan Statistic: An Application to Detect Disease Outbreaks

open access: yesApplied Sciences, 2022
The majority of the widely used scan statistics are based on distributional assumptions. Contrary to the existing methods, with a new perspective in clustering, the Mann-Whitney Scan Statistic was introduced to detect clusters in continuous data indexed ...

Measuring Spike Train Correlation with Non-Parametric Statistics Coefficient

open access: yesIEEE Latin America Transactions, 2015
Measure correlation between spike trains is a fundamental step for the study of neural systems. There are many alternatives to measure correlation, but not all possess the required properties.
