عنوان Bias corrected maximum likelihood estimation of the parameters for several unit distributions نوع پژوهش پایان نامه کلیدواژهها Bias reduction, Cox-Snell method, New unit Lindley distribution, Parametric bootstrap method, Simulation, Unit distributions, Unit gamma distribution, Unit Weibull distribution. چکیده In this thesis, we discuss the bias corrected maximum likelihood estimators for several unit distributions such as the new unit Lindley, unit Weibull and unit gamma distributions. We discuss each of these distributions and discuss bias correction problem using the Cox-Snell and parametric bootstrap methods. پژوهشگران اکبر اصغر زاده (استاد مشاور)، ساره عبدالکریم جازع (دانشجو)، سیدمحمدتقی کامل میرمصطفائی (استاد راهنما)
