A flexible approach for estimating the effects of covariates on health expenditures

Article Abstract:

A flexible approach to determine the effects of covariates on health expenditures using sequences of conditional probability functions, similar to those used in discrete time hazard rate analysis is developed. The approximate conditional density estimator provides accurate and precise estimates of derivatives of expected outcomes for a wide range of types of explanatory variables.

A longitudinal study of the effects of age and time to death on hospital costs

Robust methods are used to examine the effects of age and proximity to death on hospital costs. It is shown that the large tenfold increase in costs from 5 years prior to death to the last year of life overshadows the 30 percent increase in costs from age 65 to 85.
