相关介绍: | We propose an additive hazards model with latent variables to investigate the observed and latent risk factors of the failure time of interest. Each latent risk factor is characterized by correlated observed variables through a conrmatory factor analysis model. We develop a hybrid procedure that combines the EM algorithm and the borrow-strength estimation approach to estimate the model parameters. The consistency and asymptotic normality of the parameter estimators are established. Various nice features including nite sample performance of the proposed methodology are demonstrated by simulation studies. Our model is applied to a study concerning the risk factors of chronic kidney disease for type 2 diabetic patients. |
