Title: "Estimation and Inference with Semiparametric Models on Censored Data"
Abstract:
It is challenging to obtain variance estimates if estimating functions are nonregular, such as non-smooth and non-monotone, in particular for censored data. We discuss the issues and present Monte Carlo smoothing method for variance estimation which might not require any explicit form, not even the estimating function itself. We present general convergence theory and demonstrate the methods with examples.
