Statistical notes for clinical researchers: Evaluation of measurement error 2: Dahlberg’s error, Bland-Altman method, and Kappa coefficient

초록

In evaluation of measurement error, the intraclass correlation coefficient (ICC) is very useful in assessing both consistency and agreement as mentioned in the previous Statistical Notes. There are other useful and popular measures of measurement error,such as the Dahlberg error and Bland-Altman method for continuous variables, or the Kappa coefficient for categorical variables.
