suggestion: move log/exp combinations from StatsFuns.jl

[tpapp]

Maybe these functions could be moved to SpecialFunctions.jl.

What's wrong with having them in StatsFuns?

[tpapp]

While they are used in statistics (among many other fields), these functions are not per se statistical.

Also, because of JuliaStats/StatsFuns.jl#20, I was under the impression that that package is not for end users, while logistic, softmax, etc are useful functions on their own.

Anyway, this is just a suggestion that I thought would bring up, when revisiting the discussion for the PR above which suggested moving them to StatsBase.jl — I think SpecialFunctions.jl would be more appropriate.

[ararslan]

Yeah perhaps. (Btw, I'm not saying it's a bad suggestion, I was just wondering what your motivation was for making it. 🙂)

The plan that was discussed a while back was to move distribution-specific code in StatsFuns to Distributions, then move the rest to StatsBase. I don't have a huge preference for where functions like that end up living.

Thinking about this, maybe SpecialFunctions.jl is not the right place for them either. I think they should go to their own package, and opened a discussion in JuliaStats/StatsFuns.jl#46.
