@inproceedings{Liu2005RobitRA, title={Robit Regression: A Simple Robust Alternative to Logistic and Probit Regression}, author={Chuanhai Liu}, year={2005}, url={https://api.semanticscholar.org/CorpusID:3110460} }
Logistic and probit regression models are commonly used in practice to analyze binary response data, but the maximum likelihood estimators of these models are not robust to outliers. This paper considers a robit regression model, which replaces the normal distribution in the probit regression model with a t-distribution with a known or unknown number of degrees of freedom. It is shown that (i) the maximum likelihood estimators of the robit model with a known number of degrees of freedom are…

Convergence rates for MCMC algorithms for a robust Bayesian binary regression model
- 2012
Mathematics, Computer Science
It is proved that, under certain conditions, both algorithms converge at a geometric rate, which can be used to choose an appropriate (Markov chain) Monte Carlo sample size and allow one to use the MCMC algorithms developed in this paper with the same level of confidence that one would have using classical Monte Carlo.
Robit regression in Stata

A new command is described, robit, that implements robit regression in Stata, which replaces the underlying normal distribution in the probit model with a Student’s t distribution.

Mathematics, Computer Science
This work shows that the robit DA Markov chain is trace-class for arbitrary choices of the sample size n, the number of predictors p, the design matrix X, and the prior mean and variance parameters, which implies geometric ergodicity.
Efficient estimation and prediction for the Bayesian binary spatial model with flexible link functions

Mathematics
A Bayesian spatial robit model for spatially dependent binomial data is introduced and the approach is doing as well as the classical models for predicting the disease severity for a root disease, as the probit link is shown to be appropriate.
