该文在删失函数型协变量背景下,研究非参数模型的估计问题,通过使用曲线扩展算法把删失函数型数据扩展为完整函数型数据。该算法具有很好的准确性和灵活性,避免了删失函数型数据难以建模的问题。使用函数型核估计方法得到模型中非线性算子的估计值。通过数值模拟验证该算法的有效性和删失函数型数据对非参数模型的影响,并应用于肝硬化数据集的数据分析中。
Estimation of Nonparametric Models with Censored Functional Covariates
In this paper,we study the estimation of nonparametric models in the background of censored functional covariates,and extend censored function data to complete function data by using curve exten-sion algorithm.The algorithm has good accuracy and flexibility,and avoids the problem that the censored functional data is difficult to model.The estimation of smoothing operator in the model is obtained by the kernel estimation method.The effectiveness of the proposed algorithm,as well as the influence of the censored functional data on the nonparametric model,is verified by numerical simulation.The proposed algorithm is applied to the data analysis of cirrhosis data set.
