Bradley Efron (born May 24, 1938 in St. Paul , Minnesota ) is an American statistician . He is a professor at Stanford University and is the originator of the bootstrap method .

biography

Efron studied on a scholarship at Caltech , where he graduated in 1960. In the same year he went to Stanford, where he received his doctorate in 1964 with Rupert Miller and Herb Solomon ( Problems in probability of geometric nature ). After that, apart from visiting professorships at Berkeley , Imperial College in London and Harvard University , he stayed at Stanford.

The bootstrap method found by Efron in 1979 allows the variability of a test statistic to be estimated non-parametrically. This method is closely related to the so-called Jack-Knife method and is often used when no valid analytical approximation (such as a confidence interval based on the assumption of normal distribution) is possible. Other groundbreaking contributions from Efron deal with the empirical Bayesian method (an inference method that has both frequentistic and Bayesian features), high-dimensional multiple testing using the "false discovery rate", variable selection and model selection, and geometric aspects of statistical inference .

In July 2007, Bradley Efron received the National Medal of Science , the highest scientific award in the United States, for his contributions to theoretical and applied statistics, and in particular for the bootstrap method . He is a member of the National Academy of Sciences , the American Academy of Arts and Sciences, and the American Statistical Association . The universities of Madrid, Chicago and Oslo awarded him an honorary doctorate . He is also a McArthur Fellow and was President of the Institute of Mathematical Statistics (IMS).
