The behavior of conditional or pseudo-likelihood parameter estimates of the model parameters is investigated via simulation. A comparison using a mineralogy data set suggests that the conditionally specified model outperforms competing models (with BS marginals). An analogous comparison using a well-known data set of Australian athletes also suggests the superiority of the conditionally specified model. Further investigation of its possible general superiority is suggested.Acceso Abiertoasymmetric distributionBirnbaum-Saunders distributionconditional specificationsmultivariate distributionhttp://dx.doi.org/10.3390/sym13050762
