WebbWith $mse, we can extract the estimated Mean Squared Error (MSE) of the EBLUPs. The MSE is estimated using a parametric bootstrap procedure. To make the bootstrap results reproducible, we set a seed. The MSE is an absolute measure. Often, relative measures give us a better picture of precision.

Small area estimators are based on area level computations if models link small area means of interest (y) to area-specific auxiliary variables (such as x sample means).
