1) Could the flexibility in weighting new data you're thinking about be fit into an optional argument to update!()? 3) Agreed. Right now a few methods do the opposite of that with something like update!(obj, y::Float64) = update!(obj, [y]) I've at least started an issue for a redesign to get a

1) More flexibility is certainly good, as long as it doesn't impact performance or readability. I would also like additional flexibility on weighting new data. 2) aside from possible overflow, updating averages instead of sums is probably more performant when you call state() more often than upd

I emailed John Myles White a few months back about merging. One of his concerns was that OnlineStats looks more ambitious, but he wanted to work together. I was focused on the implementation progress to show off for my oral prelim (I'm a PhD student in statistics), so nothing ever came of it.

It looks like you've implemented a lot. I'll take a look in more depth and see how it fits in with my goals. I'm curious... is there a reason you haven't merged in some way with StreamStats? It seems to overlap pretty heavily, but maybe not. If it makes sense, are you open to collaboration

I've been working on https://github.com/joshday/OnlineStats.jl. The src/README shows the implementation progress. It's partially a playground for my research (on online algorithms for statistics). Please take a look and let me know what you think, but my regression stuff is currently in break

This is great... I haven't looked at StreamStats yet. It certainly seems like the right package to extend. I'll start a discussion there. Thanks.

I think the closest thing is https://github.com/johnmyleswhite/StreamStats.jl Now whether those operations should be in there, or built on top of it, I'm not sure. But definitely open an issue there to get a discussion going. Cheers, Iain On Friday, April 24, 2015 at 5:13:15 PM UTC-4, Tom Brelof
