A Capture-Recapture-based Ascertainment Probability Weighting Method for Effect Estimation with Under-ascertained Outcomes
Outcome under-ascertainment, characterized by the incomplete identification or reporting of cases, poses a substantial challenge in epidemiologic research. While capture-recapture methods can estimate unknown case numbers, their role in estimating exposure effects in observational studies is not well established. This paper presents an ascertainment probability weighting framework that integrates
