Dear all

I have a dataset titled "readings". This consists of readings on the same XRays by 3 different interpreters.
The readings are continuous and I am trying to assess the similarity/agreement between the 3 different interpreters.

ID Reader 1 Reader 2 Reader 3

Bland Altman and Cohens Kappa will not work as I have 3 interpreters.
I have tried using Fleiss Kappa using the kappatec code but this apparently is not appropriate for comparing continuous readings.

Just wondering if anybody had any suggestions on STATA. There are a number of agreement functions on STATA but none that take into account continuous readings by 3 different interpreters.

Many many thanks in advance
