The Neyman–Pearson lemma is part of the Neyman–Pearson theory of statistical testing, which introduced concepts like errors of the second kind, power function, and inductive behavior. [ 2 ] [ 3 ] [ 4 ] The previous Fisherian theory of significance testing postulated only one hypothesis.
Neyman-Pearson hypothesis testing made significant contributions to decision theory, which is widely employed, particularly in statistical quality control. Hypothesis testing also extended its applicability to incorporate prior probabilities, giving it a Bayesian character.
The major Neyman–Pearson paper of 1933 [11] also considered composite hypotheses (ones whose distribution includes an unknown parameter). An example proved the optimality of the (Student's) t-test, "there can be no better test for the hypothesis under consideration" (p 321). Neyman–Pearson theory was proving the optimality of Fisherian ...
In statistical hypothesis testing, a uniformly most powerful (UMP) test is a hypothesis test which has the greatest power among all possible tests of a given size α.For example, according to the Neyman–Pearson lemma, the likelihood-ratio test is UMP for testing simple (point) hypotheses.
The consistent application by statisticians of Neyman and Pearson's convention of representing "the hypothesis to be tested" (or "the hypothesis to be nullified") with the expression H 0 has led to circumstances where many understand the term "the null hypothesis" as meaning "the nil hypothesis" – a statement that the results in question have ...
Since the paired notions of type I errors (or "false positives") and type II errors (or "false negatives") that were introduced by Neyman and Pearson are now widely used, their choice of terminology ("errors of the first kind" and "errors of the second kind"), has led others to suppose that certain sorts of mistakes that they have identified ...

Jerzy Spława-Neyman (April 16, 1894 – August 5, 1981; Polish: [ˈjɛʐɨ ˈspwava ˈnɛjman]) was a Polish mathematician and statistician who first introduced the modern concept of a confidence interval into statistical hypothesis testing [2] and, with Egon Pearson, revised Ronald Fisher's null hypothesis testing.
