|a In this thesis, an additive hazard model is considered as a semiparametric model in which the unknown parameter consists of finite dimensional and infinite dimensional parts with left truncated and right censored data. Chapter 1 includes some basic definitions, theorems and some important related works. In Chapter 2, the full likelihood function for the model is obtained for the parametric part and also for the nonparametric part using linear sieve procedure and then compute the maximum likelihood estimators for the two parts. The consistency of the maximum likelihood estimators is also proved for the two type of parameters. Chapter 3 focuses on computing the score operators for the parametric and nonparametric parts and proved their linearity and continuity and compute their adjoint score operators. An efficient score function is computed using the results of martingale theory for the counting process. Finally, a simulation study using Monti-Carlo method and R language is implemented to compute the maximum likelihood estimators and compare the results of the proposed method with the true values. It is shown through the simulation results the efficiency of the proposed method to find the maximum likelihood estimators. As a real life application, Stanford heart transplant data is considered and the maximum likelihood estimators are computed. List of Published or Submitted Papers 1.
