In statistics, the Neyman–Pearson lemma was introduced by Jerzy Neyman and Egon Pearson in a paper in 1933. 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. The previous Fisherian theory of significance testing postulated only one hypothesis. By introducing a competing hypothesis, the Neyman-Pearsonian flavor of statistical testing allows i… Webbhypothesis or theory that is not novel, i.e., it is known at the time the hypothesis or theory is tested, whereas a prediction is novel insofar as it is unknown at the time the hypothesis or theory is tested (see, e.g., Maher 1988.
