The population parameters are estimated using sample surveys. However, the current investigation’s goal is to estimate subpopulations such as total through a calibration approach. proposed estimator’s properties have been given under simple random sampling. In addition, class of estimators for subpopulation has discussed. estimator evaluated theoretically and empirically in comparative study. r...

On-line analysis of output data from discrete event stochastic simulation focuses almost entirely on estimation of means. Most “variance estimation” research in simulation refers to the estimation of the variance of the mean, to construct confidence intervals for mean values. There has been little research on the estimation of variance in simulation. We investigate three methods for point and i...
