In order to compute error-components 3SLS estimates of this model, which requires different instruments for different equations, we propose a generalization of the Fuller-Battese transformation to ...

In this context, three examples of the copula approach are given: the first is algebraic (the Logistic-Exponential stochastic frontier model with margins bound by the Farlie—Gumbel—Morgenstern copula) ...

We conclude that, generally in epidemiology, clear differention between classical and Berkson error components is essential in the assessment of error sources and for establishing an error model ...
