Inter-Rater Reliability for Stata Users

Stata users now have a convenient way to compute a wide variety of agreement coefficients within a general framework.  The module KAPPAETC can be installed from within Stata and computes various measures of inter-rater agreement and associated standard errors and confidence intervals. 

A very interesting background article entitled "Implementing a general framework for assessing interrater agreement in Stata" by Daniel Klein is certainly a must read for Stata users who want to understand the calculations performed by KAPPAETC behind the scene. KAPPAETC is a Stata package that was remarkably well written, and  is what I strongly recommend to all Stata users for calculating the the AC1, Kappa, Krippendorff agreement coefficients and associated standard errors, and confidence intervals.
