Comparing Measures of Location When the Underlying Distribution Has Heavier Tails than Normal
Öz
In this study, two conventional (mean and median) and three robust (trimmed mean, one-step M-estimator and modified one-step M-estimator) measures of location are compared in terms of their asymptotic relative efficiencies and mean squared error when the underlying distribution is contaminated normal.
