* Investigated methodologies of tipping point analysis for missing binary outcomes departing from missing at random assumption * Developed a R-Shiny app for assessing efficacy and safety of an investigational drug in phase III trial. * Explored positive evidence of a study at the interim stage according to some quantities, such as consistency, conditional power as well as predictive power by borrowing historical prior information. * Conducted simulations to prove the consistency between two while-alive estimands and LWYY estimators for recurrent events terminated by death under the assumption of multi-state models in chronic heart failure clinical trial.
