Details
A total of 43 psychiatrists provided diagnoses. In the actual study (Sandifer, Hordern, Timbury, & Green, 1968), between 6 and 10 psychiatrists from the pool of 43 were unsystematically selected to diagnose a subject. Fleiss randomly selected six diagnoses per subject to bring the number of assignments per patient down to a constant of six.
As there is not a fixed set of six raters the ratings from the same column
are not related to each other. Therefore, compared to the dataset with the
same name in package irr
, we applied a permutation of the six ratings.
