Hirotsugu Akaike (赤池 弘次, Akaike Hirotsugu, IPA: [akaike çiɾotsɯɡɯ], November 5, 1927 – August 4, 2009) was a Japanese statistician.[1] In the early 1970s, he formulated the Akaike information criterion (AIC). AIC is now widely used for model selection, which is commonly the most difficult aspect of statistical inference; additionally, AIC is the basis of a paradigm for the foundations of statistics. Akaike also made major contributions to the study of time series. As well, he had a large role in the general development of statistics in Japan.
