NumPyro now has several excellent introductory examples with no direct counterparts in Pyro. Porting one of these to Pyro would be a great way for someone to simultaneously learn more about Bayesian data analysis and make a valuable open source contribution.

If you are reading this and want to give one of them a try, please leave a comment here so that other peo

Are there any plans to add a Zero-Inflated Poisson (ZIP) and Zero-Inflated Negative Binomial (ZINB) to TFP? Those are usually very common distributions in other packages, and it shouldn't be hard to implement.

Ankit Shah and I are trying to use Gen to support a project and would love the addition of a dirichlet distribution

Dear Numpyro developers,

Please develop Euler Maruyama features in numpyro similar to features found in PyMC.

Thanks alot.

The current example on MDN from Edward tutorials needs small modifications to run on edward2. Documentation covering these modifications will be appreciated.

Hi,

Looks like there is support for lots of common distribution. There are a handful of other distributions which are not presently supported but could (fingers crossed) be easily implemented. Looking at [Stan's Function Reference] I see...

• Beta Binomial
• [Chi-Square](https://mc-stan.org/docs/2

There are a variety of interesting optimisations that can be performed on kernels of the form

k(x, z) = w_1 * k_1(x, z) + w_2 * k_2(x, z) + ... + w_L k_L(x, z)

A naive recursive implementation in terms of the current Sum and Scaled kernels hides opportunities for parallelism in the computation of each term, and the summation over terms.

Notable examples of kernels with th

Rather than trying to rebuild all functionality from Distributions.jl, we're first focusing on reimplementing logdensity (logpdf in Distributions), and delegating most other functions to the current Distributions implementations.

So for example, we have

distproxy(d::Normal{(:μ, :σ)}) = Dists.Normal(d.μ, d.σ)

This makes some functions in Distributions.jl available through

Hey 👋

You are here because you considered contributing to blackjax for at least a split second. Thank you! But sometimes we are just not quite sure what to work on/don't want to bother the maintainer. We've been there. That is why we put together a list of the projects that are up for grabs on blackjax.

**You can pick any of these, open an issue to signal you are working on it and
