Development in small area estimation and major issues confronted

Abstract

Studies indicate that there is no single approach to providing small domain estimation with satisfactory results for all situations. The-size and homogeneity of the small area domain, the availability of external information, whether the variable of interest is continuous or discrete, the explanatory power of any assumed relationship, and the power level to discriminate event occurrences will affect the properties of any estimate. An approach that is suitable in one situation may not be suitable in another.
