Abstract:
|
The framework for this talk is right censored linear regression for a case cohort design. We compute the semiparametric information bound and use an augmented estimator to improve asymptotic efficiency over the commonly used but inefficient Horvitz-Thompson estimator. The asymptotic properties of the augmented estimator are derived and simulation results shown.
