This paper examines multivariate Tobit system with Scale mixture disturbances. Three estimation methods, namely Maximum … Simulated Likelihood, Expectation Maximization Algorithm and Bayesian MCMC simulators, are proposed and compared via generated … data experiments. The chief finding is that Bayesian approach outperforms others in terms of accuracy, speed and stability …
