<Bradley Efron>'s work connects statistical theory, computation and applications. His <bootstrap> estimates a statistic's sampling uncertainty by repeatedly sampling from the <empirical distribution> and recalculating that statistic. For example, resampling the observed data and recomputing a <median> produces a simulated <sampling distribution> without requiring a <normal distribution>[normal population model]. Validity still depends on the statistic and sampling setting; the method is not automatically correct for every extreme-value or dependent-data problem.
His bootstrap work has distinct records as a July 1977 Stanford technical report and a January 1979 journal article.<Bootstrap Methods: Another Look at the Jackknife by Bradley Efron, BIO 32 technical report>[Stanford catalogue, BIO 32 and July 1977 report date]{ref}<Bootstrap Methods: Another Look at the Jackknife by Bradley Efron, 1979 journal article>[Annals of Statistics 7(1), 1–26, January 1979 bibliographic record]{ref} His Stanford profile describes research spanning theoretical statistics, biostatistics and astrophysical applications.https://statistics.stanford.edu/people/bradley-efron[Institutional profile, research interests]{ref}
