Abstract:
|
In this talk, we consider a semiparametric threshold regression model with flexible covariate effects. Specifically, we propose a B-spline approximation method to estimate nonlinear covariate effects on both the initial state and the rate of the process. Some graphical and numerical procedures are presented for model checking. Simulation studies are conducted for practical situations, and the methodology is applied to a study of knee osteoarthritis that motivated this investigation.
