Estimator for Coefficient of Variance About Poisson Distribution Based on a Symmetric Loss Function
Xu Bao · Journal of Hebei University · 2011
For a common statistics in application statistics named Karl-Pearson coefficient of variance,we dealt with the form and property of its Bayes estimator based on a symmetric loss given a set of poisson sample,we also discussed the admissibility and inadmissibility of a class of linear estimators.The simulation results showed that the Bayes estimator of Karl-Pearson coefficient of variance in this paper performed well about the precision,it could be used in statistical decision problem.
