Inter-Rater Reliability using the SAS System
Kilem Li Gwet, PhD

I wrote this book, primarily to assist researchers and students with the calculation of various inter-rater reliability coefficients using the SAS system. For categorical ratings, you will learn how to use SAS for computing various chance-corrected agreement coe cients (CAC) such as Cohen's kappa, Gwet's $\mbox{AC}_1$/$\mbox{AC}_2$, Krippendorff's alpha and many others. For quantitative ratings, you will learn how SAS can be used to compute different variants of the Intraclass Correlation Coefficient (ICC).
