Hi All, I am looking for a generalization of Mcnemar's test to k*k tables (k>2). I came across the Stuart-Maxwell test in R (concord package) which seemed to do what I want but was unable to find any documentation/formula on it. Also are there tests for k*k tables (k>2) for ordinal data? For example I have 2 judges each grade a student's paper (A-E), giving a 5*5 table of ordinal counts where A is better than B,...E. Any pointers/references most welcome. regards, Mary --------------------------------- Yahoo! Messenger with Voice. Make PC-to-Phone Calls to the US (and 30+ countries) for 2¢/min or less.
