The vegetation and water resources model for encamped had 95% of model support and was 5.75 AICc units better than the next best model, which only had a model weight (w) of 0.05 (Table 3).
(DOCX 19 kb) Additional file 4: Ranking of candidate models (representing all possible combinations of the five predictors in each global model) by AICc, along with relative log-likelihood (RLL), ΔAICc, and model Akaike weights (w i ) for: a) home range and b) group size.
The weights of evidence (w+ i ) for each predictor were calculated by summing the model AIC c weights (w i ) over all models in which each term appeared.
Each derived model, with associated weights w N and performance, is reported in Table 3.> -wrap-foot> Models 1 and 2 were trained on ICs_total and BSA_total, respectively, with a better performance of the ICs-based model (as already reported in Table 2) (root mean square errors [RMSEs] of 2.25 and 2.46 kcal/mol, for ICs and BSA, respectively).
In addition, we have included parameters that allow for further quantitative refinement of model predictions: reaction weights (W) and maximum activity values (YMAX).
Specifically, this involved fitting residual variances at unity and scaling the other terms in the model (1) with weights, w ij = EDC ij/g jjλ j, where g jj is the sire variance of the j'th country, with heritabilities provided by each participating country j and EDC ij is the bull's effective daughter contribution in country j [ 14].
Autocorrelation structures can be operationalized in statistical models as spatial weights (W ij ), wherein either centroid distance or contiguity (i.e., shared boundaries) is quantified for each observation pair.
In a stand-alone version of the density model, the weight W could be calculated by making reasonable assumptions on the values of log diameter, length, and taper.
At each scattering event, where the light-matter interaction is modeled, the weight W of the photon packet is decreased by an amount determined by the absorption coefficient µ a at the scattering location.
