Copula bivariate probit models: with an application to medical expenditures.
The bivariate probit model is frequently used for estimating the effect of an endogenous binary regressor (the 'treatment') on a binary health outcome variable. This paper discusses simple modifications that maintain the probit assumption for the marginal distributions while introducing non-normal dependence using copulas. In an application of the copula bivariate probit model to the effect of ...
متن کاملModeling the Differences in Counted Outcomes using Bivariate Copula Models: with Application to
This paper makes three contributions. First, it uses copula functions to obtain a ßexible bivariate parametric model for nonnegative integer-valued data (counts). Second, it recovers the distribution of the difference in the two counts from a speciÞed bivariate count distribution. Third, the methods are applied to counts that are measured with error. SpeciÞcally we model the determinants of the...
متن کاملWeighted Approximations of Tail Copula Processes with Application to Testing the Bivariate Extreme Value Condition
Consider n i.i.d. random vectors on R, with unknown, common distribution function F . Under a sharpening of the extreme value condition on F , we derive a weighted approximation of the corresponding tail copula process. Then we construct a test to check whether the extreme value condition holds by comparing two estimators of the limiting extreme value distribution, one obtained from the tail co...
متن کاملA test for Archimedeanity in bivariate copula models
We propose a new test for the hypothesis that a bivariate copula is an Archimedean copula. The test statistic is based on a combination of two measures resulting from the characterization of Archimedean copulas by the property of associativity and by a strict upper bound on the diagonal by the Fréchet-upper bound. We prove weak convergence of this statistic and show that the critical values of ...
متن کاملA Bivariate Latent Class Correlated Generalized Ordered Probit Model with an Application to Modeling Observed Obesity Levels
Obesity is a major risk factor for several diseases including diabetes, heart disease and stroke. Increasing rates of obesity internationally are set to cost health systems increasing resources. In the US a conservative estimate puts resources already spent on obesity at $120 billion annually. Given scarce health care resources it is important that categorisation of the overweight and obese is ...
