We simplify the implementation of some elliptical copula regression models through the normal representation. Both copula and marginal probability density functions are expressed as the scale mixtures of normals to facilitate the estimation procedure. With the fact that all elliptical...

This study examines the heterogeneous effect of income diversification on Vietnamese household welfare measured by total income and consumption expenditure. In the analysis, we use quantile regression for both pooled and cross-sectional data across regions. The effects from Simpson's diversity...
