Название: Semiparametric regression analysis on longitudinal pattern of recurrent gap times
Автор: Chen Y.Q.
In longitudinal studies, individual subject may experience recurrent events of the same type over a relatively long period of time. The longitudinal pattern of gaps between successive recurrent events is often of great research interest. In this article, the probability structure of the recurrent gap times is ﬁrst explored in the presence of censoring. According to the discovered structure, we introduce the stratiﬁed proportional reverse-time hazards models with unspeciﬁed baseline functions to accommodate individual heterogeneity, when the longitudinal pattern parameter is of main interest. Inference procedures are proposed and studied by way of proper riskset construction. The proposed methodology is demonstrated by the Monte Carlo simulations and an application to a well-known Denmark schizophrenia cohort study data set.
