“…To our knowledge, no earlier study in the literature has considered the CML method in the context of unorderedresponse models (rather, all earlier studies have used the CML approach for multivariate models such as the multivariate binary probit or the multivariate ordered probit (see, for example, Renard et al, 2004, Zhao and Joe, 2005, Varin and Vidoni, 2006, Feddag and Bacci, 2009, Bhat and Sener, 2009, Varin and Czado, 2010, Bhat et al, 2010a. This is because the CML method by itself is not well suited to unordered-response models and does not provide substantial computational benefits in unordered-response models; rather, it is our specific proposal in this paper to combine the CML method with the normal orthant probability approximation method of the previous section that is the key to computational benefits.…”
