报告题目:Semiparametric Varying-coefficient Model for Interval Censored Data with a Cured Proportion
报告摘要:Varying-coefficient models have claimed an increasing portion of statistical research and are now applied to censored data analysis in medical studies. We incorporate such flexible semiparametric regression tools for interval censored data with a cured proportion. A two-part model is adopted to describe the overall survival experience for such complicated data. To fit the unknown functional components in the model, we take the local polynomial approach with bandwidth chosen by cross-validation. We establish consistency and asymptotic distribution of the estimation and propose to use bootstrap for inference. A BIC-type model selection method is constructed to recommend an appropriate specification of parametric and nonparametric components in the model. Extensive simulations are conducted to assess the performance of our methods. An application on a decompression sickness data illustrates our methods.
