Why do I always have to answer questions about Robbolito? Ask Roberto Pescatore!
I went through the Rybka code forwards and backwards and took many things.

I don't think so. The scores are not independent (if one of them goes up, the other goes down). So +/- 8 looks correct.

Even if the score were independent the error bar should only be multiplied by 1.4.

EDIT: Actually I am not sure. I thought that the way Bayes Elo is set up
is such that the +/- 8 really refers to the difference. But I am not sure.
It's ELOstat, and +/- 8 does really refer to difference in an individual match.

I don't see how it can apply to a "difference". What if you just publish the one rating? Then the "difference" is not shown. Isn't this based simply on standard deviation? Which would mean the +/-8 applies to the actual value in question, not how it relates to other values???

Elo always relate to other values. A +/- in the elo case will always refer to the pool in which it was examined.

Publishing one isolated value with a +/- is completely meaningless.

LOL, sorry Bob, here I have erred, I meant 10 is the difference and 8 is indeed the error in that particular match (error being 2 standard deviations, 95% confidence, as it shown in both BayesElo and ELOstat by default). Think about an individual match as that: 10 +/- 8 without a base means that you take one engine at _fixed_ Elo say 3195 (has no errors, set by the average and the difference/2 alone), then, the second engine, has 3205 +/- 8 rating. Or the other way around. When you have a rating list of many engines, you either set a base, or their average itself sets a pretty stable base, therefore this sqrt(X^2 + Y^2) for the total error.

Kai
