PearsonChiSquareTest[data] tests whether data is normally distributed using the Pearson \[Chi]^2 test. PearsonChiSquareTest[data, dist] tests whether data is distributed according to dist using the Pearson \[Chi]^2 test. PearsonChiSquareTest[data, dist,
例数大于40,且所有理论数大于5,则用普通的Pearson 检验。 例数大于40,所有理论数大于1,且至少一个理论数小于5,则用校正的 检验或Fisher’s确切概率法检验。 例数小于40,或有理论数小于2,则用Fisher’s确切概率法检验。 2×C表或R×2表资料的统计分析 列变量&行变量均为无序分类变量,则 (1)例数大于40,...
Summary Pearson's chi-square test has been widely used in testing for association between two categorical responses. Spearman rank correlation and Kendall's tau are often used for measuring and testing association between two continuous or ordered categorical responses. However, the established statistica...

The Chi-Square test (蠂2 test) is a family of tests based on a series of assumptions and is frequently used in the statistical analysis of experimental data. The aim of our paper was to present solutions to common problems when applying the Chi-square tests for testing goodness-of-fit, ...

The minimum Pearson chi-square estimator and test are defined for multinomial log-linear models with expected frequencies subject to linear constraints. The minimum Pearson chi-square estimate defined here yields predicted cell frequency estimates that, unlike the maximum likelihood estimates, minimize the...
By utilizing this result the power is obtained for specific alternative distributions in testing for normality. This enables recommendations to be made as to the number of class intervals to be employed in applying the aforementioned modification of the Pearson chi-square test of normality....
