I need some help to perform Bayesian unconditional quintile regression (Bayesian RIF regression) and Bayesian RIF decomposition. I have read the articles by Ndoye and Lubrano in this regards (file attached) however, they did not discuss the software/R-packages that they used in the analysis. so I request any body to please share/guided some helping words and software as well that might be helpful to analysis the data.
I shall be vey thank full for your support
best wishes
