The Stanford Statistics record gives report number SOL ONR 6 and report date November 1951. The catalogue metadata was inspected; the report's full text was not accessible during this pass. The record is cited for historical authorship and date, not as an inspected proof passage.
Historical source for Chernoff information 2026-10-14
Stanford's archive records a technical report by Herman Chernoff, dated November 1951, on asymptotic efficiency of hypothesis tests based on sums of observations.[ref]
A Measure of Asymptotic Efficiency for Tests of an Hypothesis Based on the Sum of Observations, technical report by Herman Chernoff. Stanford Statistics technical-report record: SOL ONR 6, author H. Chernoff, report date November 1951
This is historical source metadata, rather than a claim to have inspected the report's full proof. The modern theorem cited above connects that efficiency question to the log-likelihood ratio accumulated across repeated observations.
