Tests for equality of proportions (related samples)
Tests for the equality of proportions of related samples and their properties and assumptions.
| Test | Purpose |
|---|---|
| McNemar-Mosteller Exact | Test if two proportions are equal. 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. |
| Score Z | Test if two proportions are equal. 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. |
