1. Neyman–Pearson lemmaIn statistics, the Neyman-Pearson lemma, named after Jerzy Neyman and Egon Pearson, states that when performing a hypothesis test between two point hypotheses H0: θ = θ0 and H1: θ = θ1, then the likelihood-ratio test which rejects H0 in favour of H1 when where is the most powerful test of size α for a threshold η. If the test is most powerful for all, it is said to be uniformly most powerful (UMP) for alternatives in the set .
