Abstract:
We study the estimation of mean medical cost when censoring is dependent and a large amount of
auxiliary information is present.  Under missing at random assumption, we propose semiparametric
working models to obtain low-dimensional summarized scores.  An estimator for the mean total cost can
be derived nonparametrically conditional on the summarized scores.  We show that when either the two
working models for cost-survival process or the model for censoring distribution is correct, the
estimator is consistent and asymptotically normal.  Small-sample performance of the proposed method
is evaluated via simulation studies.  Finally, our approach is applied to analyze a real data set in
health economics.
