| Title: | Intraclass Correlations for Quantifying Inter-Rater Reliability |
|---|---|
| Description: | Calculates various intraclass correlation coefficients used to quantify inter-rater and intra-rater reliability. The assumption here is that the raters produced quantitative ratings. Most of the statistical procedures implemented in this package are described in details in Gwet, K.L.

This is a data frame containing 3 columns or more. The first column contains subject numbers (there could be duplicates if a subject was assigned multiple ratings) and each of the remaining columns is associated with a particular rater and contains its numeric ratings. |
conflev |
This is the optional confidence level associated with the confidence interval. If not specified, the default value will be 0.95, which is the most commonly-used valuee in the literature. |
This function returns a vector containing the lower confidence (lcb) and the upper confidence bound (ucb).

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.
iccdata1iccdata1
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.
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
