Airoldi. 21 0 obj When the experimental data set is contaminated, we usually employ robust alternatives to common location and scale estimators, such as the sample median and Hodges Lehmann estimators for location and the sample median absolute deviation and Shamos estimators for scale. We already made an argument that IV estimators are consistent, provided some limiting conditions are met. The following finite set conditions are always finite. Finite-sample properties of robust location and scale estimators. This chapter covers the finite or small sample properties of the, OLS estimator, that is, the statistical properties of the OLS that are valid for any, given sample size.
