Program concord implements L. I. Lin Õs concordance correlation coefficient (Lin,1989), as well as the limits-of-agreement procedure (Bland and Altman, 1986). Recently, Lin (2000) issued an erratum reporting a number of typographical errors in his seminal 1989 paper. Further, changes in Stata Version 7 required modification of concord. This note reports the effect of the errors and provides a corrected and updated program. Copyright 2002 by Stata Corporation.
