A list with class “htest” containing the following components: the value of McNemar’s statistic. the degrees of freedom of the approximate chi-squared distribution of the test statistic. the p-value of the test. a character string indicating the type of test performed, and whether continuity correction was used.

When to apply continuity correction in McNemar’s test?

In general, a continuity correction should be applied when some counts in the table are small. As a rule of thumb, this correction is typically applied when any of the cell counts are less than 5. We will perform McNemar’s Test both with and without a continuity correction, just to illustrate the differences:
