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 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.[ref]
