Kappa for multiple raters with missing values

[kathrin_r]

Hi

I wanted to ask, if someone knows how it is possible to calculate the Kappa statistics in case I have multiple raters,but some subject were not rated by all assessors. The problem with the magree-Macro is that it issues an error message as it expects the same number of raters for all subjects. I think in STATA for the case with missing values it is still possible to calculate a Kappa value. How can I do this in SAS?

Thanks in advance for your help.

Can you remove those missing obs ?

Or try PROC MI to populate these missing value.

Or using mean value to replace missing value ?
