BIOMETRICS, 58(3), 643–649.

By: H. Bang* & A. Tsiatis n

author keywords: cost analysis; estimating equation; median regression; simulated annealing; survival analysis
MeSH headings : Biometry; Colorectal Neoplasms / economics; Colorectal Neoplasms / therapy; Costs and Cost Analysis / statistics & numerical data; Health Care Costs / statistics & numerical data; Humans; Models, Statistical; Regression Analysis
TL;DR: This article proposes semiparametric procedures for estimating the parameters in median regression models based on weighted estimating equations when censoring is present and the methods are applied to a dataset for medical costs of patients with colorectal cancer. (via Semantic Scholar)

2000 journal article

Estimating medical costs with censored data

BIOMETRIKA, 87(2), 329–343.

By: H. Bang n & A. Tsiatis

author keywords: cost analysis; counting process; efficiency; martingale; missing data; semiparametrics; survival analysis
TL;DR: A class of weighted estimators which account appropriately for censoring are introduced and are shown to be consistent and asymptotically normal with easily estimated variances in a sample of individuals whose medical costs may be right censored. (via Semantic Scholar)
