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 parameter of a binomial distribution and their properties and assumptions.
Uses the binomial distribution and computes an exact p-value. The test is conservative, that is, the type I error is guaranteed to be less than or equal to the desired significance level. Recommended for small sample sizes.
Uses the score statistic and computes an asymptotic p-value. Equivalent to Pearson's X² test. Recommended for general use.
