基于MATLAB的KAPPA系数计算。The confusion matrix was used to describe the classification accuracy and to characterize the errors. Landis and Koch (1977) classified Kappa values into different categories: 0-0.20, 0.21-0.40, 0.41-0.60, 0.61-0.80 and 0.81-1, which indicates slight, fair, moderate, substantial and almost perfect agreements, respectively.
