Bayesian Model Averaging (BMA) for Variable Selection

WebThis approach is called pseudo Bayesian model averaging, or Akaike-like weighting and is an heuristic way to compute the relative probability of each model (given a fixed set of models) from the information criteria values. Look how the denominator is just a normalization term to ensure that the weights sum up to one. Webbic.glm Bayesian Model Averaging for generalized linear models.
