摘　　要：本文目的是介绍两种单向有序二维列联表资料线性趋势χ^(2)检验以及SAS与R软件实现的方法。两种单向有序二维列联表是指原因变量为R值有序变量的"R×2列联表"和结果变量为C值有序变量的"2×C列联表",对它们进行线性趋势检验分别需要采用Cochran-Armitage’s线性趋势χ^(2)检验和Lee’s线性趋势χ^(2)检验。The purpose of this paper was to introduce the linear trendχ^(2) tests for the data of the two kinds of one-way ordinal two-dimensional contingency tables and the implementation of SAS and R software.The two one-way ordered two-dimensional contingency tables referred to the"R×2 contingency table"with R values ordinal variable as the cause variable and the"2×C contingency table"with C values ordinal variable as the outcome variable.Their linear trend tests required the use of the CochranArmitage’s linear trendχ^(2) test and the Lee’s linear trendχ^(2) test,respectively.
