Multi-Model Inference R package MuMIn version 1.48.19 CRAN Task View: MixedModels (https://CRAN.R-project.org/view=MixedModels) Tools for model selection and model averaging with support for a wide range of statistical models. Automated model selection through subsets of the maximum model, with optional constraints for model inclusion. Averaging of model parameters and predictions based on model weights derived from information criteria (AICc and alike) or custom model weighting schemes.
