Step 3: Calculate the Intraclass Correlation Coefficient. A Note. I also have ID, Subject and TIME as variables longitudinal based data set, and then I run a mixed model with time as a predictor and the variable I wish to calculate the ICC with as an outcome.
Intraclass Correlation Coefficient: Definition + Example. An intraclass correlation coefficient (ICC) is used to measure the reliability of ratings in studies where there are two or more raters. The value of an ICC can range from 0 to 1, with 0 indicating no reliability among raters and 1 indicating perfect reliability among raters.
