To develop a two-part regression framework to evaluate grouped survival data subject to informative censoring using a double sampling study design.
Formulated a joint model comprising a logistic regression model for the failure hazard given covariates and a logistic regression model for informative censoring hazard given failure time and covariates.
Applied the model to a double sampling scheme combining a full follow-up (FF) sample tracked after censoring and a partial follow-up (PF) sample untracked after censoring.
Demonstrated the method on clinical wound infection data where PF subjects were censored upon hospital discharge while FF subjects were monitored post-discharge, evaluating model identifiability and sample allocation tradeoffs.
Demonstrated that incorporating a full follow-up sample resolves model identifiability limitations present when evaluating partial follow-up data alone.
Determined that the relative allocation of subjects between full follow-up and partial follow-up cohorts directly influences the precision of hazard parameter estimates.
