Need to compare the agreement between two methods.
Out put data are catogorical- Nominal data
4 types of nominal data for each method(eg: A,X,Y,Z)
Need to compare the agreement between two methods.
Cant use weigted kappa since the data are not ordinal
#Agreement method #statistical analysis #inter reter reliability
Kaumini Herath -if I understand you well- it sounds to me like a case for Cochran's Q test:

Rolando Gonzales Thank you very much for replying me. I dont think that I can apply Cochran's Q test since the response variable can take only two possible outcomes (coded as 0 and 1) .
In my case response variable is nominal(A,B,C,D like)and not in ordered levels: “normal” , “moderate”, “high”, “very high”
Kaumini Herath, interesting. Maybe ordinal GLM then, see:
