A Transformed Statistic for the Test of Conditional Independence in a \(J \times K \times L\) Table
摘要
This chapter derives an approximation of the distribution of a test statistic for conditional independence in a 3-way contingency table based on an asymptotic expansion. In order to improve the accuracy of the chi-square approximation of the test statistic for conditional independence in a 3-way contingency table, a transformed statistic is derived by using the approximation.
