An Alternate Multinomial Assessment of the Accuracy of the χ 2 Test of Goodness of Fit
卡方拟合优度检验准确性的另一种多项分布评估
Tate and Hyer [9] indicated in a recent article that the χ2 test of goodness of fit is markedly in error when expected frequencies are small, and that, moreover, errors of substance remain even with large expected frequencies. This result appears to arise from the application of an improper statistical model. When the multinomial test proposed here is substituted, it is found that errors of the χ2 test are smaller than Tate and Hyer would suggest for small expected…
