I agree that most of the arguments against including these convenience variables no longer apply, so it's worth reconsidering this. > * I couldn't find documentation explicitly discouraging the use...

There are three main ways to use softmax for simplex transforms. One uses parameter expansion to retain bijectivity: `f(y) = [softmax(y); logsumexp(y)]`. The other two come from compositional data analysis...

> I'm currently testing performance of each of these versus stick-breaking. Coming back to this, the experiment results are at https://sethaxen.github.io/simplex_transforms_results/, and I believe these results were the motivation for...

There's still a use-case for a bijector that is effectively `F = cholesky(R)` for correlation matrix `R`. Suppose one wants a parameter `F` because their model needs the Cholesky factorization,...

Is there a place where it would make sense to also document use of a learned posterior as a prior in a Pyro model? The killer app would be to...

As we discussed, a necessary but not sufficient check that things worked well when (specifically, that the learned likelihood is sufficiently accurate in the region of parameter space where Pyro's...

Doctests for `rstar` currently fail because a large number of warnings are now being raised at https://github.com/JuliaAI/CategoricalDistributions.jl/blob/7de33c24e3fa02c7f5aadecc34f70ad961a4baec/src/types.jl#L385-L394 Note that this check has always been present in CategoricalDistributions and actually predates...

For some reason, I can't seem to get the extension to work. Package precompilation fails with the [error](https://github.com/JuliaMath/AbstractFFTs.jl/actions/runs/5046767252/jobs/9052738771?pr=103#step:6:168): ```julia ERROR: The following 1 direct dependency failed to precompile: AbstractFFTs [621f4979-c628-5d54-868e-fcf4e3e8185c]...

Nevermind, it seems extensions cannot have weak deps that are also deps. In this case, the dep needs to be loaded within the extension from the main package, see e.g....
