| Outline of Final Research Achievements |
I considered variable selection for high-dimensional varying coefficient models for longitudinal data and obtained some significant results. Specifically, I proposed with collaborators a useful two-step procedure to identify the true semi-varying coefficient model of the longitudinal data. The procedure consists of the nonparametric independence screening and the group SCAD method. Besides, I proposed an efficient estimator of the constant coefficients of the true semi-varying coefficient. I proved its desirable theoretical properties and some numerical properties were also investigated in our collaborative papers. In addition, I also obtained some theoretical results for a forward variable selection procedure for high-dimensional variable coefficient models and Cox models with variable coefficients. Numerical properties were also examined in our collaborative papers.
