Hello Everyone I am calculating Fleiss Kappa, I have 28 raters, 5 Subjects and 5 ratings. The problem is that there are 2 missing values in the data. Would it better to replace those with "0" or should those be omitted? By omission I will be left wit only 3 subjects. and my second problem is that overall agreement comes to zero, whereas the data is not showing agreement to be close to zero the ratings for 4 and 5 are maximum (the ratings are 1: total disagreement and 5: Total Agreement) whereas for 1 and 2 its very less Please help me for these queries Thank you very much in advance Regards Sunita -- View this message in context: http://www.nabble.com/Fleiss-Kappa-tp24456050p24456050.html Sent from the R help mailing list archive at Nabble.com.
