Task 6.2 Adaptive Optimal Design
- A survey among EFPIA participants has identified the level of current usage of
- ptimal design software and the expectations of the industry for future
capabilities.
- Problems that will be studied:
- Model robustness (model averaging/ selection)
- Local versus Robust Optimal design (pros & cons)
- How to include the previous information in the design calculations
- Estimation
- Effect of early cohorts as the driving force in an adaptive design
- What to optimize?
- How to optimize
- Within subject adaptations vs. Between subject adaptations

Task 6.3 Diagnostic tools
New diagnostic tools are necessary for model selection and model assessment. Specific areas of interest are:
- New diagnostics for repeated time-to-event models
- Optimal covariate model building strategies
- Use of simulation techniques to assess various model diagnostics (VPC, NPC and NPDE
- f model diagnostics)
- Fit output from NLME to simpler models to help in diagnosing and building
- From visual diagnostic tools to inference and decision tools
- Sampling from conditional distributions for model assessment
