POOLING ESTIMATORS FROM EXPONENTIAL GROUPED CENSORED DATA
Ayman S. Baklizi (Jordan)
|
Abstract: This paper discusses the problem of pooling two grouped
censored data from the exponential distribution. Two shrinkage type estimators
are suggested. The first estimator uses the criterion of minimizing the mean
squared error. The other estimator is based on the p-value of an
appropriate test. The properties of the estimators are investigated using Monte
Carlo methods. It is found that the shrinkage estimators have a good performance
compared with the maximum likelihood estimator. |
Keywords and phrases: censored data, exponential distribution, mean squared error, p-values,
pooling data, shrinkage estimation. |
