Note(s): This table shows the corresponding matrix of identified extremely efficient banks across methodologies. This matrix reports on each similarity ratio of a quarter of the lowest cost efficiency of banks determined by different techniques, while the correspondence between DEA and SFA when determining the top quarter is presented in the upper right triangle
