diagnoses: Psychiatric diagnoses provided by different raters

In irr: Various Coefficients of Interrater Reliability and Agreement

Description

Psychiatric diagnoses of n=30 patients provided by different sets of m=6 raters. Data were used by Fleiss (1971) to illustrate the computation of Kappa for m raters.

Usage

data(diagnoses)

Format

A data frame with 30 observations (psychiatric diagnoses with levels 1. Depression, 2. Personality Disorder, 3. Schizophrenia, 4. Neurosis, 5. Other) on 6 variables representing different raters.

rater1

a factor including the diagnoses of rater 1 (levels see above)

rater2

a factor including the diagnoses of rater 2 (levels see above)

rater3

a factor including the diagnoses of rater 3 (levels see above)

rater4

a factor including the diagnoses of rater 4 (levels see above)

rater5

a factor including the diagnoses of rater 5 (levels see above)

rater6

a factor including the diagnoses of rater 6 (levels see above)
