cac.raw5obser

This dataset contains data from a reliability experiment where 5 observers scored 15 units on a 4-point numeric scale 
based on the values 0, 1, 2 and 3.

datasets

Calculates various chance-corrected agreement coefficients (CAC) among 2 or more raters are provided.
Among the CAC coefficients covered are Cohen's kappa, Conger's kappa, Fleiss' kappa, Brennan-Prediger coefficient, Gwet's AC1/AC2
coefficients, and Krippendorff's alpha. Multiple sets of weights are proposed for computing weighted analyses. All of these statistical
procedures are described in details in Gwet, K.L. (2014,ISBN:978-0970806284): "Handbook of Inter-Rater Reliability," 4th edition,

This dataset has 15 rows (for the 15 subjects) and 6 columns. Only the last 5 columns associated with the 5
observers are used in the calculations. Of the 5 observers, only observer 3 scored all 15 units. Therefore, some missing
ratings in the form of "NA" appear in the columns associated with the remaining 4 observers.<dl class="dl-horizontal">
