LONG Bing(Department of Mathematics and Physics,Jingchu University of Technology,Jingmen Hubei 448000,China)
Firstly,density function of order statistics is given about Эрланга distribution,calculate related characteristic numbers of the order statistics.Secondly,in the missing data samples unbiased estimation approximate maximum likelihood estimation and confidence interval of parameter are given.In the end,several estimations of the parameter are calculated through an instance,and its superiority is proved.
