A note on concordance correlation coefficient.
In this note, we first review some recent developments about measures of agreement, which are often required in medicine and other sciences, with focus on differences between these methods. In the last part, we mention five important concerns when using a newly developed concordance correlation coefficient. Our conclusion is that we need to be especially careful when using existing correlation methods and a new correlation method needs to be developed in the future.
