WebOct 23, 2009 · The McNemar test tests the null hypothesis that conditional on b + c, b has a binomial (b + c, 1/2) distribution. The proper way to test the null hypothesis is to apply the one-sample binomial test. If there is no association between b and c values, then the probability is 0.5 that the sample 1 and sample 2 pair falls in the. WebJun 1, 2024 · Since this data was paired, it was analyzed using McNemar's chi-squared for paired proportions with the exact McNemar significance probability. Counts, proportions, and 95% confidence intervals were reported. All analyses were performed using Stata 14.2 (College Station, TX). A p-value of <0.05 was considered significant. Ethics and funding

WebAlthough a statistical test might commonly use an approximation, it does not mean it cannot be calculated using the true probability distribution. For example, an asymptotic p-value … The mid-P McNemar test (mid-p binomial test) is calculated by subtracting half the probability of the observed b from the exact one-sided P-value, ... When b + c < 6, the exact-P-value always exceeds the common significance level 0.05. The original McNemar test was most powerful, but often slightly liberal. ...
