Roadmap

PyMC4 Development Roadmap

MVP

• Example suite
• model.sample_posterior
• pm.Plate for hierarchical models

Up Next

• model.prior_predictive
• model.posterior_predictive

TFP Collab/Help

• parallel_for for model log probability
• Better HMC tuning, e.g. mass matrix adaptation

Longer-Term

• Particle Samplers/SMC
• Polya-gamma sampler
• xarray integration
• Symbolic PyMC
