Irish statistician, founder of the CSO and the ESRI
Robert (Roy) Charles Geary (April 11, 1896 – February 8, 1983)[1] was an Irish mathematician, statistician and founder of both the Central Statistics Office and the Economic and Social Research Institute. Geary is known for his contributions to the estimation of errors-in-variables models,[2] Geary's C, the Geary–Khamis dollar, the Stone–Geary utility function, and Geary's theorem,[3] which has that if the sample mean is distributed independently of the sample variance, then the population is distributed normally.[4][5][6]
