摘要：
This study deals with the estimation of parameters of the weighted exponential distribution with presence of outliers. The maximum likelihood and moment of the estimators are derived. These estimators are compared empirically using monte carlo simulation when all the parameters are unknown. There Bias and MSE are investigated with help of numerical technique. © 2011 Asian Network for Scientific Information.
