As discussed on Slack, it would be good to have an additional specialization of `logdensity` that takes `NamedTuple`-valued inputs. The Turing main repo already [implements](https://github.com/TuringL…

NestedSamplers is an independent sampler library at the moment and lacks an interface for models specified by the domain-specific language (DSL) in [Turing](https://github.com/TuringLang/Turing.jl). H…

DynamicPPL contains a series of integration tests in [the `test/turing` directory](https://github.com/TuringLang/DynamicPPL.jl/tree/master/test/turing).
The way it's set up in CI, it fetches the mo…

We are by default using `pathfinder.jl` to pre-heat our NUTS sampling by providing an (approximate) sample from the posterior distribution as the initial point for NUTS warm-up, as per [here](https://…

> The PR made me wonder whether it would be possible to improve performance of `with_logabsdet_jacobian` for `SimplexBijector` by not performing `transform` and `logabsdetjac` separately when both are…

Currently, these distributions are broken due to https://github.com/FluxML/Zygote.jl/issues/873. As discussed in https://github.com/TuringLang/Bijectors.jl/pull/155, the corresponding tests are marked…

Often an MCMC fit stalled on one chain, or starts to diverge only on, it would be helpful to figure out a way we can report some posteriors from the chains as they come in, rather than all at once at …

`Distributions.logpdf` is only defined for single samples (and not multiple samples) whereas `logpdf_with_trans` is defined for sets of samples as well. To be consistent with the behaviour in Distribu…

binv = Bijectors.inverse(b)
x = randn(StableRNGs.StableRNG(23), (3, 3))
f = x -> sum(b(binv(x)))
