What are the Limitations of Kaplan-Meier Estimators?
While Kaplan-Meier estimators are powerful, they do have limitations. One major limitation is that they do not account for covariates—factors that could influence survival probabilities, such as patient demographics or disease characteristics. Additionally, Kaplan-Meier curves can become less reliable with small sample sizes or a high degree of censoring. Advanced statistical methods, such as the Cox proportional hazards model, may be needed to address these limitations.
