gigg: Group Inverse-Gamma Gamma Shrinkage for Sparse Regression with Grouping Structure
A Gibbs sampler corresponding to a Group Inverse-Gamma Gamma (GIGG) regression model with adjustment covariates. Hyperparameters in the GIGG prior specification can either be fixed by the user or can be estimated via Marginal Maximum Likelihood Estimation.
