Paul S. Dwyer

Paul Sumner Dwyer (born December 8, 1901 in Chester , Pennsylvania , † September 17, 1982 ) was an American statistician and mathematician ( linear algebra ).

Life

Dwyer graduated from Pennsylvania State College with a bachelor's degree in 1923 and taught there as an instructor from 1921 to 1926. In 1926 he became an assistant professor at Antioch College , in 1929 an associate professor and in 1932 a professor. He received his doctorate in 1936 at the University of Michigan under Harry C. Carver (1890–1977) ( Combined expansions of products of symmetric power sums, and of sums of symmetric power products with application to sampling ), after having worked there from 1927 in the summer worked at Carver. He was from 1937 as a research assistant at the University of Michigan, was there in 1938 Assistant Professor, 1942 Associate Professor and 1946 Professor. In 1946 he founded a statistical research laboratory at the university with Cecil C. Craig, which in 1968 became the department of statistics. In 1971 he retired.

He dealt with the application of the theory of symmetrical functions in statistics and also with linear algebra (matrix calculation) and emphasized in an essay (Dwyer, Waugh, On errors in matrix inversion, JASA 1953) the necessity, as a statistician, of numerical errors in the linear Take algebra into account. In this context he is counted among the pioneers of interval arithmetic with his textbook on linear algebra from 1951 . He was also interested in the use of computers (at first punch card machines) for the necessary extensive calculations in statistics.
