Chi-square Fisher’s Exact Test Just as there is a computationally intensive exact test of one proportion (based on the Binomial), there is an exact test in this setting, based on a discrete distribution called the Hypergeometric; it is based on the distribution of Σ X given that all of the marginal totals are fixed Σ x Σ y S = Σ x + Σ y n – Σ x m – Σ y F = n + m – S n m n + m Test of Two Proportions We want to test H :0λ X λ Y under the null The test: If the calculated quantity is greater than 3.8415, we reject the null of λX= λY The level of this te
