Abstract:

The maximum likelihood estimator (MLE) and several different pivots will be used to construct different confidence intervals for the logistic location parameter. These confidence intervals will be constructed by using simple random sampling (SRS) and ranked set sampling (RSS). Difference confidence intervals will be compared via their expected lengths and the standard deviation of their lengths using simulation. We expect that the confidence intervals base on RSS to have shorter expected lengths and smaller standard deviation from there competitors using the SRS.
