What happened to the RAPM website?

It now just lists a bunch of teams and the RAPM for this season and the on-off.

[blabla]

What kind of information is missing that you are interested in?

[nikomCH]

It used to list the RAPM data for seasons from 2001-present. There is no way to get that information now.

Everything, actually. All the data that was there that made the site useful historically is currently missing. I'm glad I copied as much as I did from the site while the other stuff was up, but I didn't get everything.

From what I can gather, J.E. has been tinkering with some new stats that may yield superior predicative power than RAPM.

I assume it'll all be back up soon

[Rerisen]

These numbers look changed drastically from last year? I.e. If anyone remembers the big Rose/Deng thread on the PC board, now we are seeing a complete reversal there, and many other players having gone up or down.

Edit - Reading the link above, obvious big effect from the box score influence. Perhaps not to be called 'the RAPM website' anymore.

Right, we're having this debate on a thread on the PC board, and I'm currently explaining my vehement disapproval on the APBRmetrics board. Just started having this discussion yesterday so I don't want to jump the gun, but I'm quite alarmed.

It's interesting because when I first got into all this stuff, I had major fights over on APBR where guys there just didn't see value in +/- stats. I had thought we'd gotten past these issues, but right now it seems to me like the guys who actually know enough to make the stats don't really understand why other people like using them so much. Kind of flabbergasted.

Any news about this? I need a fix of non-boxscore stuff.

So I guess RAPM is dead then?

[nikomCH]

No it's been brought back but it's not the same stat as before, it's been renamed as xRAPM and has become more of a statistical plus minus.

Yeah so it's dead.

How is that different from what it was previously? Is it possible to explain in layman's terms?

[Doormatt]

From what I understand he uses the box score to prior inform his RAPM (meaning something to base it off of) whereas before I believe it was non prior informed or RAPM informed. Either way the old version had absolutely nothing to do with the box score.

That's half of what he's done.

He's taken the stat that you've described and blended it with the old "prior-informed" RAPM. That's what's listed on his site. It's essentially an average of a box-informed RAPM and the old RAPM

[Doormatt]

He says it's more accurate but the whole point of RAPM is to give us something outside of the box score so it doesn't make sense to me.
