Penalized small area models for the combination of unit- and area-level data

Burgard, Jan Pablo; Krause, Joscha; Münnich, Ralf T. - 2019

The joint usage of unit- and area-level data for model-based small area estimation is investigated. The combination of levels within a single model encloses a variety of methodological problems. Firstly, it implies a critical decrease in degrees of freedom due to more model parameters that need...
