Returns:

==================================================
          Intraclass Correlation Results
==================================================
Model: twoway
Type: agreement

Subjects = 20
Raters = 3
ICC(A,1) = 0.20

F-Test, H0: r0 = 0 ; H1 : r0 > 0
F(19.00,39.75) = 1.83, p = 0.0543

95%-Confidence Interval for ICC Population Values:
-0.039 < ICC < 0.494
==================================================

Another simple example:

from pyirr import read_data, kappam_fleiss

data = read_data("anxiety")  # loads example data
kappam_fleiss(data, detail=True)

Returns:

==================================================
            Fleiss` Kappa for m Raters
==================================================
Subjects = 30
  Raters = 6
   Kappa = 0.430

       z = 17.652
 p-value = 0.000

                         Kappa       z  p.value
