Variance Estimation of Nominal-Scale Inter-Rater Reliability with Random Selection of Raters

Autor: Kilem L. Gwet

Publikováno v: Psychometrika. 73:407-430

Most inter-rater reliability studies using nominal scales suggest the existence of two populations of inference: the population of subjects (collection of objects or persons to be rated) and that of raters. Consequently, the sampling variance of the

A comparison of Cohen’s Kappa and Gwet’s AC1 when calculating inter-rater reliability coefficients: a study conducted with personality disorder samples

Autor: Danny Wedding, Tinakon Wongpakaran, Nahathai Wongpakaran, Kilem L. Gwet

Publikováno v: BMC Medical Research Methodology

Background Rater agreement is important in clinical research, and Cohen’s Kappa is a widely used method for assessing inter-rater reliability; however, there are well documented statistical problems associated with the measure. In order to assess i
