Abstract: In this study, we consider the estimation of the location parameter and the scale parameter of the shifted Gompertz (SG) distribution. We obtain the closed form estimators of these parameters by using the modified maximum likelihood (MML) methodology originated by Tiku (1967). We also compare the efficiencies of these estimators with the well-known and widely used least squares (LS) and maximum likelihood (ML) estimators via Monte-Carlo simulation study in terms of bias, mean square error (MSE) and deficiency (Def) criteria. In addition, we eva...
