A Test of Symmetry Based on the Kernel Kullback-Leibler Information with Application to Base Deficit Data The assumption of the symmetry of the underlying distribution is important to many statistical inference and modeling procedures. This paper provides a test of symmetry using kernel density estimation …

Methods Improving the Estimate of Diagnostic Odds Ratio Diagnostic odds ratio is defined as the ratio of the odds of the positivity of a diagnostic test results in the diseased population relative to that in the non-diseased population. It is a function of …

Rank-Based Kernel Estimation of the Area Under the ROC Curve In medical diagnostics, the ROC curve is the graph of sensitivity against 1-specificity as the diagnostic threshold runs through all possible values. The ROC curve and its associated summary indices a …

More Efficient Logistic Analysis Using Moving Extreme Ranked Set Sampling Logistic regression is the most popular technique available for modeling dichotomous-dependent variables. It has intensive application in the field of social, medical, behavioral and public health sci …

On Stratified Bivariate Ranked Set Sampling with Optimal Allocation for Naïve and Ratio Estimators The purpose of the current work is to introduce stratified bivariate ranked set sampling (SBVRSS) and investigate its performance for estimating the population mean using both naïve and ratio methods. …

On Inference of Partially Correlated Data

Neuroprotective Core Measure 2: Partnering with Families – Effects of a Weighted Maternally-Scented Parental Simulation Device on Premature Infants in Neonatal Intensive Care We sought to explore the effects of neuroprotective care with use of weighted maternally-scented parental simulation device on 24–38 week gestation infants in a level III NICU. A sample of 45 infants …
