Key Points

To review the theoretical principles, methodological developments, and practical implementations of robust small area estimation, while outlining critical unresolved statistical problems.
Synthesized theoretical frameworks and statistical models designed to improve subpopulation inference when local survey sample sizes are sparse.
Evaluated robust estimation paradigms that accommodate extreme outliers and protect against misspecified model assumptions.
Robust small area estimation frameworks successfully limit outlier influence and reduce estimation bias when classical normality assumptions are violated.
Key theoretical and computational challenges persist in robust mean squared error estimation, high-dimensional data integration, and spatial-temporal modeling.

Implication

Methodological review evaluates robust small area estimation techniques in survey subpopulations, highlighting strategies to mitigate outlier sensitivity and model misspecification.

Abstract

Small area estimation (SAE) is an important statistical subfield broadly focused on improving inference for non-overlapping subpopulations, or areas, when the available sample yields small area-spe...
