W opracowaniu jest analizowany problem predykcji frakcji i średniej w domenie z wykorzystaniem modeli nadpopulacji bez zmiennych dodatkowych uwzględniających podział populacji na warstwach. W rozważaniach symulacyjnych uwzględniono problem wpływu zlej specyfikacji modelu nadpopulacji i szacowania liczebności populacji na dokładność predykcji. (abstrakt oryginalny)

Survey research in practice is often based on non-random samples what implies that the model approach should be used. What is more, in many surveys no information is available on auxiliary variables for non-sampled elements of population. One of the key issues in this case may be a problem of model misspecification too. In this paper two proposals of predictors of domain means and fractions based on models without auxiliary variables are studied including the problem of accuracy in the case of model misspecification and estimating subpopulations sizes.
