 Title: Study on Robustness of Correlated Frailty Model Authors: Atanasov, Dimitar Keywords: frailty modelsrobust maximum likelihood estimation Issue Date: 2005 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Pliska Studia Mathematica Bulgarica, Vol. 17, No 1, (2005), 5p-12p Abstract: This study considers a robust properties of correlated frailty models. The dependence between related individuals must be considered in order to be studied the difference between the gene information and the environment as causes of death. To do that, one can introduce the frailty parameter Z, which can be decomposed as Z =Zg+Ze, where Zg represents the frailty, due to the gene information, and Ze represents the influence of the environment. Using the WLTE(k) one can obtain a robust maximum likelihood estimation of the unknown parameters of the model. Description: 2000 Mathematics Subject Classifi cation: 62J12.
