RORM: Robust Ordinal Response Model via Divergence Approach

This repository provides the R code implementing the robust inference for the ordinal response model via the divergence approach, as proposed by the following paper.

The repository includes the following files.

• robustORM.R: The script implementing the proposed inference methods for the ordinal response model with the density-power and $\gamma$-divergences
• links.R: The script containing functions that compose several density and distribution functions
