^a The difference between the given model and the minimum QAIC model for that cover type. Models with values ≤2 have substantial support from the data, values from 3–7 have considerably less support, and differences ≥10 have essentially no support (Burnham and Anderson 2002: p. 70).

^b Akaike weight of evidence, or probability, that model is the actual �best� among models within the cover type.

^c Number of parameters in the model.
