A Marginalized Diffusion Model for Estimating Age at First Endoscopy Examination from Current Status Data

Abstract:
We propose an approach for estimating the age at first endoscopy examination from current status data collected via two series of cross-sectional surveys. To model the national probability of ever having an endoscopy, we incorporate birth cohort effects into a mixed-influence diffusion model. We link a state-specific model to the national-level diffusion model using a marginalized modeling approach. In future research, results from our model will be used as microsimulation model inputs to estimate the contribution of endoscopy examinations to observed changes in colorectal cancer incidence and mortality.
