To perform a pairwise comparison between two models, one can convert ΔAICi into an evidence ratio, which gives the odds that one model provides a better fit to the data relative to the other. Ratios of less than 5:1 indicate slight evidence, ratios between 5:1 and 30:1 indicate moderate to strong evidence, and ratios in excess of 30:1 indicate very strong evidence (Burnham & Anderson, 2002). Model comparison through evidence ratios is straightforward and, unlike NHST, can support continuous rather than dichotomous quantification of evidence (Wagenmakers & Farrell, 2004).
