Sum weights of independent variables across models (AIC)
Hello,
I'd like to sum the weights of each independent variable across linear
models that have been evaluated using AIC.
For example:
> library(MuMIn)
> data(Cement)
> lm1 <- lm(y ~ ., data = Cement)
> dd <- dredge(lm1, beta = TRUE, eval = TRUE, rank = "AICc")
> get.models(dd, subset = delta <4)
There are 5 models with a Delta AIC Score of
