Estimating the VA total health care cost using a semi-parametric heteroscedastic two-part model


Journal Article

To appropriately assess the impact of the establishment of community-based outpatient clinics (CBOCs) on the total health care costs in a VA study, we need to deal with three methodological problems inherent in the data. The first problem is skewness of the data. The second one is zero costs for some patients. The third one is heteroscedasticity. We proposed a semi-parametric heteroscedastic two-part transformation regression model to deal with these problems, and the proposed model would allow us to explicit model heteroscedasticity. © Springer Science+Business Media, LLC 2006.
