Sažetak

(ne postoji na srpskom)
In this paper we examine the behavior of the generalized likelihood ratio test for the structural parameter in frailty models used in the case of complicated observational schemes such as arbitrarily censored and truncated data. The sizes and powers of the tests are given and compared under different circumstances, e.g. under misspecification of the frailty distribution among others.
