Historical source for Chernoff information (source code)

= Historical source for Chernoff information

Stanford's archive records a technical report by <Herman Chernoff>, dated November 1951, on asymptotic efficiency of hypothesis tests based on sums of observations.<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]{ref} 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.
