摘要: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.
