Residual-Based Sieve Maximum Full Likelihood Estimation for the Proportional Hazards Model.
Journal Article Commun Stat Theory Methods · May 16, 2026 The partial likelihood approach is the gold standard approach for estimating regression parameters in proportional hazards model, largely because it avoids specifying the baseline hazard function. However, this approach can lack robustness in the presence ...

Journal Article Stat Med · May 2026 When the proportional hazards assumption does not hold, the hazard ratio can misrepresent treatment effects in survival analysis. We evaluate the win ratio, originally proposed for prioritizing multiple outcomes, as an effect size measure for a single surv ...

Conference Journal of Clinical Oncology · March 1, 2026 Lack of standardized reporting and collection of patient-reported outcomes (PROs) limits cross-trial comparisons of first-line IO-based regimens for mRCC. Prospectively collected real world data may fill this important knowledge gap. Pts with stable/improv ... Full text CiteRecent Grants
