We propose two estimation techniques. The rst type of estimators, including ordinary least squared (OLS) estimator and weighted least squared (WLS) estimators, are obtained using martingale arguments. The second type of estimator, called the maximum likelihood (ML) estimator, is obtained via EM algorithm that treat the survival times of left censored observations as missing. Simulation study indicated the ML estimate is more ecient than both OLS and WLS estimators Pao-Sheng Shen 沈葆聖 2015 學位論文 ; thesis 16 en_US
