iccdata1: Scores assigned by 4 judges to 5 targets/subjects.
In irrICC: Intraclass Correlations for Quantifying Inter-Rater Reliability

Description Usage Format Source

This dataset contains data from a reliability experiment where 4 judges scored 5 subjects on a continuous scale. Some of these 5 subjects were rated multiple times. Subject 1 for example was rated 3 times by judges 1, 3 and 4, and twice by judge 2. This explains the number of records being larger than the number of subjects.

iccdata1

This dataset has 12 rows (for the 5 subjects) and 5 columns. All 5 columns are mandatory when using the ICC functions of this package. None of the 4 judges scored all 5 subjects. Judge 4 for example did not score subject 3. Moreover, the subjects scored by all judges did not receive the same number of ratings. Therefore, some missing ratings in the form of "NA" appear in the columns associated with the remaining all judges.

Target: This variable represents the target or subject number and may contain duplicate value to indicate multiple ratings assigned to the same subjects by the same judge
J1: All ratings from judge 1
J2: All ratings from judge 2
J3: All ratings from judge 3
J4: All ratings from judge 4
