Description

Summary:

The reference manual says that the hyperspherical and stick breaking constructions are the same, but we should qualify that to say that they're only the same in the sense that both produce uniform distributions over simplexes.

Additional Information:

See https://discourse.mc-stan.org/t/simplex-transform-an-hyperspherical-cooridnates/30021

Current Version:

v2.18.0

Research direction

Locate the statement in the reference manual that says the hyperspherical and stick-breaking constructions are the same, then read the linked Discourse discussion for the intended distinction. Qualify the wording so it says they are equivalent only in producing uniform distributions over simplexes, and build or review the rendered manual to confirm the clarification.
