Abstract. Program concord implements L. I. Lin’s 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.
