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).

"WebbSmall area estimation (SAE) can be used for estimating U5MR in district/municipality level by using a mixed model. The model that is often used is generalized linear mixed model (GLMM). Direct estimation of U5MR produces a large proportion of zero values (excess zero), so the Poisson model is not suitable for modeling the data. " - Small area estimation with excess zero

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.
