报告摘要:This paper is concerned with feature screening for the ultrahigh dimensional additive models with longitudinal data. The quadratic inference function (QIF) is utilized to construct the marginal screening measurement which is more efficient and robust than some parametric model assumption for the working covariance matrix in each subject or experimental unit. The sure screening property is established. Monte Carlo simulation studies are conducted to examine the performance of the proposed procedure and a real data application is also conducted to evaluate and illustrate the proposed methods.
