This is internal, users should only use reshape.

Suggested change

Distributions.ReshapedDistribution

[abhro]

The docstring for reshape does link to ReshapedDistribution, and I added this so that the cross-reference link has a target. Should I remove the @ref to ReshapedDistribution from the reshape docstring instead?

[devmotion]

Yes, probably it should be removed from the docstring. I assume the intention was to explain the default fallback but as mentioned in the docstring that one is not exported and its constructor shouldn't be used.

[devmotion]

This is already covered by

Distributions.jl/src/common.jl

Lines 450 to 460 in 8c7dd0d

	"""
	loglikelihood(d::Distribution{ArrayLikeVariate{N}}, x) where {N}
	The log-likelihood of distribution `d` with respect to all variate(s) contained in `x`.
	Here, `x` can be any output of `rand(d, dims...)` and `rand!(d, x)`. For instance, `x` can
	be
	- an array of dimension `N` with `size(x) == size(d)`,
	- an array of dimension `N + 1` with `size(x)[1:N] == size(d)`, or
	- an array of arrays `xi` of dimension `N` with `size(xi) == size(d)`.
	"""

Hmm. I did basically copy it from that docstring, to cover the docstring requested in univariate.md, line 76. Should the signature for that method be replaced with the method defined in common.jl? It did seem weird that there was a docstring listing for a method that didn't have those specific types, but I wasn't sure if there was a specific documentation need that was served, with the implementation still being the same somehow.

[devmotion]

Hmm, no, the generic method is the relevant one in this case as well. I'm not sure what's the best way to handle this.
