Abstract | ||||
This work concerns with the estimation of scale parameters and mixture proportion of two gamma distributions. Using maximum likelihood and weighted least. Squares methods the estimation is carried out when the data are ungrouped and censored. A simulated data is used to compare the maximum likelihood and weighted least squares estimators. Some examples are also introduced to study the effect of the censoring time on the estimators and the proportion mixture on the scale parameters estimates. | ||||
