Some Estimators for the Pareto Distribution
We derive some shrinkage test-estimators and the Bayes estimators for the shape parameter of a Pareto distribution under the general entropy loss (GEL) function. The properties have been studied in terms of relative efficiency. The choices of shrinkage factor are also suggested.
متن کاملOn the Maximum Likelihood Estimators for some Generalized Pareto-like Frequency Distribution
Abstract. In this paper we consider some four-parametric, so-called Generalized Pareto-like Frequency Distribution, which have been constructed using stochastic Birth-Death Process in order to model phenomena arising in Bioinformatics (Astola and Danielian, 2007). As examples, two ”real data” sets on the number of proteins and number of residues for analyzing such distribution are given. The co...
متن کاملEstimation of the variance of percentile estimates
The asymptotic formula for the variance of a percentile estimate is inversely proportional to the square of the probability density function evaluated at that percentile. In this note we show, for small and moderate sample sizes, that the estimate of the variance can have a moderate to large coefficient of variation even when the form of the density is known. When the density must be estimated ...
متن کاملPercentile Matching Estimation of Uncertainty Distribution
This paper considers the application of method of percentile matching available in statistical theory of estimation for estimating the parameters involved in uncertainty distributions. An empirical study has been carried out to compare the performance of the proposed method with the method of moments and the method of least squares considered by Wang and Peng (J. Uncertainty Analys. Appl. 2, (2...
