% For a square contingency table @var{x} of data cross-classified on
% the row and column variables, McNemar's test can be used for testing
% the null hypothesis of symmetry of the classification probabilities.
%
% Under the null, @var{chisq} is approximately distributed as chisquare
% with @var{df} degrees of freedom.
%
% The p-value (1 minus the CDF of this distribution at @var{chisq}) is
% returned in @var{pval}.
%
% If no output argument is given, the p-value of the test is displayed.
