МАТЕМАТИКА

In this paper, the maximum likelihood and the Bayes estimators under symmetric and asymmetric loss functions are derived for sample from the Kumaraswamy distribution in the presence of outliers, using Newton-Raphson method and Lindley's approximation (L-approximation). These estimators are compared empirically using Monte Carlo simulation, when all the parameters are unknown.

In this paper, we obtain Bayesian and non-Bayesian estimators for the scale parameter, reliability and failure rate functions of the Rayleigh distribution in the cases of progressively type II censored samples. The Bayes estimators are obtained using symmetric and asymmetric loss functions. Comparisons are made between these estimators using Monte Carlo simulation study..
