报告内容:

This paper considers the semiparametric estimation of the accelerated failure time (AFT) model for the interval-censored data with informative observation times. Most of the existing methods can only deal with the situation when the failure time of interest and the observation times are independent, but this assumption may not be true in practice. Corresponding to this, we proposed a sieve maximum likelihood approach for the estimation problem considered here. In the method, we employ the copula model to describe the relationship between the failure time of interest and the observation times, and we utilise the I-spline functions to approximate the unknown functions in the model. Simulation studies are carried out to examine the finite sample performance of the proposed approach. An illustrative example is also presented.
