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.

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. 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.
