Known throughout the world as coauthor of the Neyman–Pearson theory of testing statistical hypotheses, and responsible for many important contributions to problems of statistical inference and methodology, especially in the development and use of the likelihood ratio criterion. Has played a leading role in furthering the applications of statistical methods — for example, in industry, and also during and since the war, in the assessment and testing of weapons.^{[6]}
