Abstracts

EN
A computationally attractive method of estimation of parameters for a class of frailty regression models is discussed. The method uses maximum likelihood estimation for the classical exponential regression model. Scaled Fisher consistency is shown to hold and a simulation study indicating good asymptotic properties of the method, as well as real data case analysis, are presented.

W artykule omówiono atrakcyjną obliczeniowo metodę estymacji parametrów dla klasy modeli regresyjnych z nieobserwowaną zmienną „frailty”. Dowiedziono, że estymator największej wiarygodności stosowany w klasycznym wykładniczym modelu regresji jest Fisherowsko zgodny z dokładnością do skali w rozważanym modelu „frailty”. Przeprowadzone badania symulacyjne oraz analiza rzeczywistych danych wskazują na dobre własności asymptotyczne prezentowanej metody estymacji.
