This robust regression is defined by Huber M-estimators. These estimators are biased so that the Mean Square Error is calculated for each estimators to obtain which one is more efficient. This comparison shows that the ratio estimator involving of coefficient curtosis the more efficient then othersotherSimple Random SamplingRobust RegressionMean Square ErrorOther
