Improved parameter estimation in rayleigh modelMahdi, Smail (Avtor) In this paper we describe and present results on the parameter point estimation for the scale and threshold parameters of the Rayleigh distribution. Five estimating methods have been investigated, namely, the maximum likelihood, the method of moment, the probability weighted moments method, the least square method and the least absolute deviation method. Modified maximum likelihood estimators for the parameters are also proposed. Simulation studies have shown that the modified likelihood estimator outperforms the estimators obtained with the other methods except in the case of very small samples.20062014-07-11 13:01:52Delo ni kategorizirano8442UDK: 303ISSN pri članku: 1854-0023COBISS_ID: 25330781sl
