On the basis of the orthogonal decomposition of On the basis of the orthogonal decomposition of Pearson’s chi-square test statistics, a new
testing method is proposed to investigate the association between two categorical variables.
The approximate sampling distributions of the proposed test statistics were studied by using
intensive Monte Carlo simulation. Two examples are used to demonstrate the application of
the proposed method.
