  4. Explain your experience with statistical analysis plans (SAPs).

    • Answer: I have significant experience in developing, reviewing, and implementing SAPs. This includes defining the statistical methods, specifying the analyses to be performed, outlining the handling of missing data, and detailing the criteria for assessing statistical significance. I ensure the SAP aligns with the study protocol and regulatory guidelines.

  5. How do you handle missing data in clinical trials?

    • Answer: The approach to handling missing data depends on the nature and extent of the missingness (MCAR, MAR, MNAR). Methods I employ include multiple imputation, maximum likelihood estimation, and sensitivity analyses. The chosen method is always documented and justified in the SAP and statistical report.

  6. What are your experiences with survival analysis?

    • Answer: I have extensive experience with survival analysis techniques, including Kaplan-Meier estimation, Cox proportional hazards models, and accelerated failure time models. I can interpret the results of these analyses and communicate them effectively to both statistical and non-statistical audiences.

  7. Explain your understanding of linear and non-linear regression.

    • Answer: I'm proficient in both linear and non-linear regression techniques. I understand the assumptions underlying each model and can assess the model fit and interpret the results. I can also choose the appropriate regression model based on the nature of the data and research question.

  8. How do you handle outliers in your data?

    • Answer: I use a combination of visual inspection (box plots, scatter plots) and statistical methods (e.g., Cook's distance, studentized residuals) to identify outliers. I carefully investigate the reasons for outliers and decide on the appropriate course of action, which may include removal, transformation, or keeping the outlier and explaining its potential impact on the analysis.

  9. What is your experience with the FDA and other regulatory agencies?

    • Answer: I have experience preparing statistical sections of regulatory submissions (e.g., INDs, NDAs, BLAs) for the FDA and other relevant agencies. I understand the requirements for reporting statistical analyses and am familiar with the expectations for transparency and completeness.
