Is there no module in D for statistics functions such as mean, median,
mode, standard deviation, linear least squares, etc. There are codes on
Rosetta Code but a) they seem a bit inconsistent in style; and b) they
are not in a module available for use.

Have you tried dstats
https://github.com/DlangScience/dstats

Now with actually working API docs: https://dlangscience.github.io/dstats/api/

That makes me happy!

It occurs to me that I don't know how much dstats works with ndslices?

Short story: it doesn't have any explicit support. Ndslice is much newer than dstats.

The ndslice range interface should mean quite a lot of stuff will work anyway.

Is there any activity to update and improve. Some of the code looks strange. But then I realise who the original author was for much of it, and think "what am I misunderstanding".

Should we be organising a short sprint on this somewhere in London so as to get activity moving?
