Abstract
Looping through experiment design via Assurance, through Sensitivity Analysis and Meta-analysis

Experiment Design Workflow in PyMC

This project added three new demonstrations to the PyMC Examples site, staged above as a Boschian triptych of the experimentation lifecycle. The learning loop, plan, interpret, synthesize, then plan again with what you learned, is central to the Bayesian experimentation workflow.

  • → Assurance Planning via Simulation
  • → Sensitivity Analysis for Unmeasured Confounding
  • → Multiple Experiments & Bayesian Meta-analysis
  • …
  • → Assurance Planning via Simulation

Each notebook jumps off a theme in the FDA’s guidance on how to plan, probe and consolidate information derived from an experimentation programme.

  • Bayesian Assurance: here

  • Bayesian Sensitivity Analysis: here

  • Bayesian Meta-analysis: here

They will ideally be read as a learning loop.
