Akaike: an information criterion for statistical model identification

What changed

Model comparison gained a compact operational estimate of expected information loss.

Scientific scope

Exact 1974 publication and Akaike's criterion; origin in 1971, later small-sample AICc and other variants distinct.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is Akaike’s exact 1974 paper and its model-identification criterion. Earlier maximum-likelihood and information-theory work, later corrections and variants, and every use of AIC remain separate.
