We construct twelve marginal--copula combinations using three marginal distributions (normal, <italic>t</italic> and <italic>S_U </italic>-normal) and four types of copulas (normal, skewed normal, <italic>t</italic> and skewed <italic>t</italic>). Bivariate empirical evidence shows that the choice of marginal distribution plays a more important role in the Value...

This study introduces Johnson's SU-normal distribution which can accommodate the flexibility of true error distribution to obtain consistent estimates in an endogenous switching regression model. Simulation results indicate that the SU-normal model outperforms the normal model for the...
