在文献中已经提出了许多方法来建模倾斜的医疗保健成本和使用数据。本文比较了八个替代估计，包括OLS和GLM估计和一个和两个部分的模型，在预测医疗保险费用的性能。它发现，四个替代品在实践中产生非常相似的结果。然后，它提出了一个有效的方法，研究人员使用时，选择估计的医疗保健费用。(C)2004 Elsevier B.V.保留所有权利。
Many methods for modeling skewed health care cost and use data have been suggested in the literature. This paper compares the performance of eight alternative estimators, including OLS and GLM estimators and one- and two-part models, in predicting Medicare costs. It finds that four of the alternatives produce very similar results in practice. It then suggests an efficient method for researchers to use when selecting estimators of health care costs.
