Lin's Concordance Correlation Coefficient (CCC)

[Simwinga Simwinga]

Hello everyone,
How can Lin's Concordance Correlation Coefficient (CCC) be computed in Stata?

[Mike Lacy]

Often (but not always) a straightforward use of Stata's -search- command, with some of the words of interest, will lead to a helpful answer. Trying that never hurts, and in the current situation, it works well:

search concordance coefficient lin

brings you to the user-written -concord- command, for which the -help- says "concord computes Lin's (1989, 2000) concordance correlation coefficient for agreement ... ." You may then install and use this command.

-search lin concordance- reveals the -concord- command as part of Stata Journal 10(4):691 by Steichen & Cox. To install, -net sj 10-4 st0015_6-.

Edit: Crossed with #2

I think you've made a typo by inserting a backslash (/).
