We are receiving a lot of questions about relevant analyses in the Analyse-it Method Validation edition to help in evaluating new diagnostic tests in the fight against COVID-19. Below are some quick links that will help, but contact us if you have questions - we are working as normal.

Tests for the equality of proportions of related samples and their properties and assumptions.
Uses a binomial distribution and computes an exact p-value. The exact p-value is conservative, that is, the actual rejection rate is below the nominal significance level.
Recommended for small sample sizes or sparse data.
Uses the score statistic and computes an asymptotic p-value.
Note that the two-sided Score Z test is equivalent to McNemar's X2 test.
