## Abstract

In this article, we describe the hcost program for estimating mean health care costs and incremental cost-effectiveness ratios with possibly censored data. hcost estimates the mean survival time and the mean costs, as well as their variances and covariance, for a given time horizon. If the group variable is specified, hcost will report the differences between two groups, as well as the incremental cost-effectiveness ratio and its confidence interval (optional). hcost can estimate the mean costs using two methods corresponding to different types of data: the Bang and Tsiatis (2000, Biometrika 87: 329-343) estimator using only the total costs or the Zhao and Tian (2001, Biometrics 57: 1002-1008) estimator when cost-history data are available. The hcost program can also be used to specify the annual discounting rates for survival time and costs.
