Hi! Is this feature request accepted and if so, can I work on it?

[kgryte]

@dorrin-sot Hey! This feature request is accepted, and you are more than welcome to work on it. Two reference packages which can serve as templates for implementing this feature:

• dnanmeanwd
• dmeankbn

Can you give me 24-48 hours, though, before you commence work on this feature? I want to update the above two packages, as we currently do the native add-ons differently now elsewhere in the project and need to align, more generally, @stdlib/stats/base.

I will circle back when I am finishing updating the packages so you have clean references to serve as templates for implementing this feature.

Thanks for your interest in working on this!

[dorrin-sot]

Sure thanks, though since I have to resolve an issue for an assignment (in about 24 hours 🥲) I'll look around for similar feature requests.

[kgryte]

Okay! No worries! Thanks for stopping by.

Hi, I'd like to work on this if it's still up :)

Looking at the discussion, I also wanted to confirm if the reference implementations are up-to-date now.
