摘要: Exact conditional tests of independence in cross-classification tables are formulated based on theχ 2 statistic and statistics with stronger operational interpretations, such as some nominal ordinal measures association. Guidelines for the table dimensions sample sizes which economically implemented a computer given. Some selected marginal distributions used numerical comparison between significance levels approximate exact statistic.
