Weighted Kendall’s W

Weighted Kendall’s W is proposed by Mahmoudi et al. (2022) to check the agreement among raters while the importance of raters is not equal.

Weighted Kendall’s W is proposed by Mahmoudi et al. (2022) for the first time to check the agreement among raters while the importance of the raters is not equal. The original Kendall’s W (Kendall's coefficient of concordance) cannot consider the weights of the raters. It is a critical factor when the priority of the raters is not equal. When the weights of the raters are distributed equally, the value of Weighted Kendall’s W is equal to Kendall’s W. Therefore, this MATLAB file can solve both Weighted Kendall’s W and Kendall’s W. This file is very accurate and can consider the tie ranks perfectly. If you face any problem executing the code, please contact Amin Mahmoudi: [e-mail].
