%% Cross-Tabulate Independent Data Vectors % Copyright 2015 The MathWorks, Inc. %% % Generate two independent vectors, |x1| and |x2|, each containing 50 % discrete uniform random numbers in the range |1:3|. rng default; % for reproducibility x1 = unidrnd(3,50,1); x2 = unidrnd(3,50,1); %% % Cross-tabulate |x1| and |x2|. [table,chi2,p] = crosstab(x1,x2) %% % The returned |p| value of |0.1097| indicates that, at the 5% significance % level, |crosstab| fails to reject the null hypothesis that |table| is % independent in each dimension.
