With large sample sizes, Yates' correction makes little difference, and the chi-square test works very well.

WebIf the p-value is lower than our chosen significance level, we can reject the null hypothesis that the two model's performances are equal. Continuity Correction Approximately 1 year after Quinn McNemar published the McNemar Test [1], Edwards [2] proposed a continuity corrected version, which is the more commonly used variant today: WebThe Yates correction is a correction made to account for the fact that both Pearson’s chi-square test and McNemar’s chi-square test are biased upwards for a 2 x 2 contingency table. An upwards bias tends to make results larger than they should be. If you are creating a 2 x 2 contingency table that uses either of these two tests, the Yates ... WebA continuity correction applied to a chi-squared contingency table test. Normally only applied for a 2×2 table, where the effect is greatest and by a happy coincidence the arithmetic required is the simplest.
