I would like to know how you determine the f12, f21 parameters for use in the McNemar`s test when for example I have two confusion matrices such as below:
(where f12 = number of cells misclassified by A but not by B And f21 = number of cells misclassified by B but not by A)
In the example with the two confusion matrices from above, I have the totals but am having difficulty in correctly determining the matrix elements f11, f12, f21, f22 below. Thanks for your help.
