Akaike Information Criterion (AICc), delta AIC and Akaike weights for models with different autocorrelation structures (assuming no autocorrelation (OLS), ARMA(1,0), ARMA(2,0) and Compound Symmetry).

The Ordinary Least Squares (OLS) model does not allow for temporal autocorrelation. The Akaike weights can be interpreted as the “relative likelihood of the model, given the data” [50]. dBC: average distance to the centroid group; βNES: Nestedness component.
