Abstract Limited dependent variable models, including truncated regression models, have traditionally been estimated by the method of maximum likelihood. The conventional optimization algorithms; which is known as Quasi-Newton algorithm namely BFGS Quasi-Newton algorithm is used to reach the optimum values for estimated parameters. In this paper, the nature-inspired algorithm is employed to improve the numerical optimization algorithms to better estimation. Our Monte Carlo simulation results suggest that our proposed improving can bring significant improvement relative to others, in terms of mean squared error and prediction mean squared error.
