With a list of candidate WLR models, AIC table is generated (see WLR_fit; Russell et al. 2007, Latif et al. 2016).
1 | WLR_AICtable(data, mods, Obs = "Nest", AICc = T, w = NULL)
|
data |
Data frame with one column indicating which observations are use (1) versus non-use (0), and additional columns containing habitat covariates to be used as predictors in the model. All covariates listed in any elements of 'mods' must appear in this data frame. |
mods |
List of candidate models. Each element of this list should be a character string in the format "x1+x2+...". Best if generated from 'varCombosLinear' function. |
Obs |
The name of the column in 'data' indicating use-nonuse, i.e., y in the formula y~x. |
AICc |
If TRUE (default), the small-sample corrected version of AIC (AICc) is calculated. Otherwise, AIC is calculated. |
w |
Optional argument passed to WLR_fit. |
Generates AICc (or AIC) table for candidate models. Also sorts by AICc, and generates delta-AIC and model weights.
Data frame with 5 columns: Model = string representing the model (element of 'mods'), AICc (or AIC) = the information criterion for ranking models, K = the number of parameters in each model, dAIC = the difference in AICc from the top-ranked model, and m_wt = AIC-based model weight.
