摘要
In this paper,the properties and goodness of fit of exponential ratio type estimatorproposedbyKhanetal.(SciInt(Lahore)26(5):1897–1902,2014)havebeen carried out through simulation.It has been shown that estimator is consistent;the con-vergence of mean and variance of the estimator are discussed.The properties of some existing estimators based on simulation study have also been discussed.Goodness of fit test on the estimator has been carried out using Kolmogorov–Smirnov,Anderson–Darling,Cramer–von MisesandChi-squarestatistics.Fewstandarddistributionssuch as normal,Student t,Weibull and Cauchy distributions are fitted on the estimator.The best-fitted distribution on the estimator turned out to be normal distribution.
