A note on the linearly weighted kappa

Cohen’s quadratically weighted kappa is higher than linearly weighted kappa for tridiagonal agreement tables

Cohen’s weighted kappa is a popular descriptive statistic for measuring the agreement between two raters on an ordinal scale. Popular weights for weighted kappa are the linear weights and the quadratic weights. It has been frequently observed in the literature that the value of the quadratically weighted kappa is higher than the value of the linearly weighted kappa. In this paper this phenomeno...

Cohen's linearly weighted kappa is a weighted average

An agreement table with n ∈N≥3 ordered categories can be collapsed into n−1 distinct 2×2 tables by combining adjacent categories. Vanbelle and Albert (Stat. Methodol. 6:157–163, 2009c) showed that the components of Cohen’s weighted kappa with linear weights can be obtained from these n−1 collapsed 2× 2 tables. In this paper we consider several consequences of this result. One is that the weight...

Nurse-Physician Agreement on Triage Category: A Reliability Analysis of Emergency Severity Index

Background and Objectives: MThe Emergency Severity Index (ESI) triage is commonly used in clinical settings to determine the patients’ emergency severity. However, the reliability of this index is not sufficiently explored. The present study examines the inter-rater reliability of ESI by comparing triage ratings as performed by nurses and physicians. Methods: This prospective cross-sectional st...

Simultaneous Monitoring of Multivariate Process Mean and Variability in the Presence of Measurement Error with Linearly Increasing Variance under Additive Covariate Model (RESEARCH NOTE)

In recent years, some researches have been done on simultaneous monitoring of multivariate process mean vector and covariance matrix. However, the effect of measurement error, which exists in many practical applications, on the performance of these control charts is not well studied. In this paper, the effect of measurement error with linearly increasing variance on the performance of ELR contr...
