This article discusses regression analysis of failure time under the additive hazards model, when the regression coefficients are time-varying. The regression coefficients are estimated locally based on the pseudo-score function [12] in a window around each time
point. The proposed method can be easily implemented, and the resulting estimators are shown to be consistent and asymptotically
normal with easily estimated variances. The simulation studies show that our estimation procedure is reliable and useful.
