Old methods of treating missing data, such as LOCF, are now being robustly challenged by global regulators. It is clear from recent FDA, NRC & ICH documentation that a new approach to missing data is going to be required. Increasingly multiple imputation is seen as offering a strong solution.
Tipping point analysis is novel approach to examining sensitivity analysis around the imputed missing data. This tipping point approach was used in advisory committee meetings with the FDA and has already been instrumental in gaining approval for a medical device (Liublinska, V. and Rubin, D.B. (2014)).
