Edwin James George Pitman (29 October 1897 – 21 July 1993) was an Australian mathematician who made significant contributions to statistics and probability theory.
In particular, he is remembered primarily as the originator of the Pitman permutation test, Pitman nearness and Pitman efficiency. His work the Pitman measure of closeness or Pitman nearness concerning the exponential families of probability distributions has been studied extensively since the 1980s by C.
R.
Rao, Pranab K.
Sen, and others.The Pitman–Koopman–Darmois theorem states that only exponential families of probability distributions admit a sufficient statistic whose dimension remains bounded as the sample size grows.
