IGG-package: Inverse Gamma-Gamma

Description Details Author(s) References


This package contains the functions, igg and igg.normalmeans, for implementing Bayesian linear regression, sparse normal means estimation, and variable selection with the inverse gamma-gamma (IGG) prior, as introduced by Bai and Ghosh (2018) <arXiv:1710.04369>

This package implements the IGG model for sparse Bayesian linear regression and the normal means problem. Our package performs both estimation and model selection. The igg and igg.normalmeans functions also returns the endpoints of the credible intervals (i.e. the 2.5th and 97.5th percentiles) for every single parameter of interest, so that uncertainty quantification can be assessed.
