Interesting tour of Akaike’s information criterion (AIC)

Interesting tour of Akaike’s information criterion (AIC) and its relationship with (log-)likelihood ratio tests, by Chris Sutherland et al. (in press).

My fav bit is where the authors show that an improved AIC for a model comparison where the bigger model has just one extra parameter is equivalent to p < .157 on the LR-test – because simple arithmetic.
