Confirmatory Inference and Robustness
TipWhat this section covers
This section presents how I approach confirmatory statistical inference with attention to error control, missing data, assumptions, and robustness, including sensitivity analyses that support credible interpretation.
Overview
Confirmatory analysis is not just about producing p-values—it is about delivering conclusions that are:
- Statistically valid — aligned to prespecified objectives and inferential strategy
- Transparent — assumptions and limitations are clearly documented
- Robust — conclusions are assessed under alternative assumptions where appropriate
- Traceable — analysis choices connect cleanly to SAP, datasets, and outputs
This section shows how I think about confirmatory rigor in a practical, study-delivery setting.
What you’ll find in this section
Multiplicity
- Family-wise error considerations and testing strategy
- Hierarchical and structured testing concepts
- Practical implications for interpretation and reporting
Missing Data
- Missingness considerations and analytic consequences
- Method selection aligned to endpoint and design context
- Documentation of assumptions and limitations
Sensitivity Analyses
- Role of sensitivity analyses in confirmatory interpretation
- Alternative assumptions and stress-testing conclusions
- Consistency checks for decision support and reporting
Representative confirmatory contributions
- Inference planning: help align hypotheses, testing order, and reporting logic
- Risk identification: flag assumptions that may materially affect interpretation
- Missing data strategy support: connect endpoint context to defensible analysis choices
- Robustness framing: define sensitivity analyses that are meaningful, not just procedural
Working style
I treat confirmatory analysis as a discipline of consistency:
- Align inferential goals with SAP language
- Separate prespecified analyses from exploratory follow-up clearly
- Make assumptions visible and reviewable
- Evaluate robustness in a decision-relevant way
- Communicate results with both rigor and interpretability
