Abstract:
|
For most substantive relevant ecological inference problems scholars face a R x C table from which only the marginals
can be observed. We argue that most frequent used ecological inference methods are computationally demanding and are inefficient since they do not make use of all the information that is available. We take a fresh look at an estimator that was precisely developed for these kinds of problems: EMax. This estimator utilizes more available information at the estimation stage than previous ecological inference estimators in the literature. As methodological innovation that remedy the main disadvantage of EMax in substantive applications, we derive model-based standard errors. Further we examine their validity by means of a simulation study and demonstrate their use in an application to the estimation of split-ticket voting in New Zealand voting districts. |
