Title: Illness-death and marginalized frailty models with application to incident and prevalent event data Authors:  Malka Gorfine - Tel Aviv University (Israel) [presenting]
Abstract: A cross-sectional sampling design is considered which is limited to a certain age group (e.g. 40-70), with a follow-up period until death or censoring, whichever comes first. The various sources of possible bias, in estimating the covariates effect on survival, will be discussed. Unbiased estimators will be presented, based on illness-death frailty-based models. The models and methods will be applied using Biobank data with genetic variants as covariates.
