Webb31 aug. 2024 · Small area estimation (SAE) is an important problem in survey sampling when the sample sizes are not large enough to provide reliable estimates in small domains or areas. See Rao and Molina ( 2015) and Pfeffermann ( 2013) for overviews and recent developments in SAE. 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.

Domains can be defined by regional, temporal, or demographic aspects, as well as combinations of these three. For example, we can define our domains of interest as the cross-combinations of 5 states X 5 age classes X 12 months (total of 300 domains).
