To examine the theoretical and practical difficulties that general right censoring introduces into the statistical analysis of survival data.
Formulated a general mathematical framework for censored-survival processes, partitioning models into noninformative and informative censoring classes.
Evaluated the performance of likelihood-based inference, model testing, and the K-sample problem under noninformative censoring models.
Analyzed the mathematical nonidentifiability of censoring mechanisms and the consequences of misclassifying informative censoring as noninformative.
Standard survival analysis methods heavily depend on noninformative censoring assumptions, leaving inferences vulnerable when these conditions fail.
Mathematical nonidentifiability prevents researchers from empirically verifying whether censoring is informative or noninformative using survival data alone.
Falsely assuming noninformative censoring introduces systematic bias into survival distribution estimates and distorts hypothesis tests.
