Tools for univariate and multivariate generalized linear models with model averaging and null model technique (Nakamura et al. 2015).
The package provides functions to estimate the relative importance of predictor variables in univariate and multivariate generalized linear models. The relative importance predictor variables is calculated by summing the Akaike weights of all models in which that predictor variable is included (Burnham & Anderson, 2002). The sum of the Akaike weights indicates the importance of a variable in explaining variation in a given dataset, relative to other predictor variables included in the analysis. The significance of each predictor variable can be assessed by the null model approach.
The key functions in this package are the following.
maglmModel averaging for GLM based on information theory.
mamglmModel averaging for multivariate GLM based on information theory.
ses.maglmStandardized effect size of relative importance values for * model averaging GLM.
ses.mamglmStandardized effect size of relative importance values for model averaging mutlivariate GLM.
