Johnson compare their estimator to two other existing multi-equation duration models developed by Boehmke, Morey, and Shannon (2006) and Chiba, Martin, and Stevenson (2015) and point out that their estimator differs from existing models. They should have, however, acknowledged that Boehmke’s (2006) estimator is the closest to theirs. The authors were unfortunately unaware of Boehmke’s (2006) estimator when they developed theirs. His application is a seemingly unrelated regression and theirs is an instrumental-variable regression, but the underlying estimators are essentially the same. The primary difference is that Chiba and Johnson’s model is derived as a special case within a flexible copula framework that allows them to specify and estimate models with different distributional assumptions. For example, in addition to the probit–log normal model that was developed in Boehmke (2006), Chiba and Johnson derived and estimated probit-Weibull and probit–log logistic specifications to choose the best-fitting model. This is consistent with one of the suggested directions for future research proposed by Boehmke (2006, 437).ReferencesBoehmke, Frederick J. 2006. “The Influence of Unobserved Factors on Position Timing and Content in the NAFTA Vote.” Political Analysis 14 (4): 421–38.First citation in articleCrossrefGoogle ScholarBoehmke, Frederick J., Daniel S.
