From Wikipedia, the free encyclopedia

Roy C. Geary was an Irish statistician who lived from 1896 to 1983. He held degrees from University College Dublin and the Sorbonne. He was the founding director of the Central Statistics Office (Ireland) (in 1949). He was head of the National Accounts Branch of the United Nations in New York from 1957 to 1960. He was the founding director of the Economic and Social Research Institute (in 1960).

He is known for Geary's C, the Geary-Khamis dollar, the Stone-Geary utility function, and Geary's Theorem[1], which has that if the sample mean is distributed independently of the sample variance, then the population is distributed normally.[2]
