# Insufficient-Gibbs-Sampling


`InsufficientGibbs` is a package that enables users to sample from the posterior parameters when only certain robust statistics of the data are accessible. The paper that comprehensively describes the theory behind these methods can be found on arXiv (https://arxiv.org/abs/2307.14973). Additionally, the code responsible for generating all the paper figures can be located in the `figures` folder.

## Robust Gibbs package

We propose here three main functions named `Gibbs_med_MAD`, `Gibbs_med_IQR` and `Gibbs_Quantile` to cover the case when we observe the pairs (median, MAD) or (median, IQR) or a sequence of quantiles.
