Re: EIDRaS Ratings

Thanks. Last issue before I can post a proper comparison: There are some users (e.g. shaun.thompson) who are listed as banned in the csv dump you posted but are included in the Ghost Rating and are not banned on the site so I think the GR list must be grabbing the banned list from another (more corr...

Re: EIDRaS Ratings

Are games under a certain length excluded (i.e. 3 turns or less)?

I'm trying to reconcile the games played and am running into issues.

Re: EIDRaS Ratings

Cool, I'll tell the script to ignore them for now. You might have missed my edit but I also need the weighting for Known World. I assume 0.25?

Re: EIDRaS Ratings

@RJ Yeah, but I suppose the average rating could shrink as well in each game. At any rate, I imagine the rating inflation is dwarfed by the inflation caused by low-rated players leaving the site. We could curve everybody's rating to keep the site wide average at 1000 but I'm not sure if that's neces...

Re: EIDRaS Ratings

The other player gets a significant boost to their webDip ranking under both systems, but the difference is how it impacts you. Both of these are zero-sum systems, so he can't gain more than what you loose. Not to bog things down but they aren't exactly zero sum. Expected scores are based on an 'ex...

Re: EIDRaS Ratings

First of all, Elo is a name - not an acronym so you it doesn't need to be all caps. Like others have said, GR is quite simple to understand. At the start of the game, everybody 'bids' a fraction of their rating and that makes up the pot. So, the pot is bigger if you play against better people but yo...

Re: EIDRaS Ratings

CCR, you are correct for assuming I got it wrong. So, does it work like this? For PPSC: Solo: -winner gets 18/34 (or solo count/number of centres for variants) -Losers get centreCount/survivorCentres Draw: -1/drawSize That seems crazy. Is that really the case? PPSC is dumb if it is. For SoS: Solo: -...

Re: EIDRaS Ratings

For PPSC (and SoS) do people score:
(a) their number of supply centres divided by the total number of SCs
or
(b) their number of supply centres divided by the total number of SCs in the draw?

This only really affects games where there is a resign and not all the SCs are in the final draw pool.

Re: EIDRaS Ratings

Yup, I look forward to bitter debate over how we should rank no-press ancient med maps against live full press world map games.

Also, I wasn't sure how to deal with rulebook press. I gave it the same rating as full press. For the sake of rankings, I imagine I can just combine rulebook and full press?

Re: EIDRaS Ratings

What I'd really like to add is for the code to track people's ratings over time but it would make the code very cumbersome (because Matlab and me) and I may run into memory issues. That could answer some of these questions.

Re: EIDRaS Ratings

Hang on. Why on earth do judge give live games such a low weighting?!? I guess because people can play so many of them? I'm happy to play around with the ratings which is why I posted this before I was completely done. I just put some in to start. edit: Yup, using legacy nomeclature because I don't...

Yeah, all non-WTA is simply excluded at the moment. I'll get to it later this week. Feel free to put the code wherever you like.

Re: EIDRaS Ratings

@Aereaux Will this take into account users that have taken over a power after it CDed? Unfortunately this is restricted to the same data that is scraped for GR. I believe that means I only have information on who finishes the games, not who starts them. Also, you should make them avaiable as a csv ...

EIDRaS Ratings

Thanks to ghug's dump in the other thread, I have started calculating the EIDRaS ratings for the site. You can access the Excel sheet with the ratings I've calculated so far as well as the MATLAB code I'm working on by clicking here: https://drive.google.com/drive/folders/1zXPUM28MKDoTJICDj7tSx37V-Y...

Re: January Ghost Ratings Published

Aereaux, thanks. CCB, I believe the issue is that the code that scrapes the system for results doesn't track replacements. There's a lot of work for the few people who spend time working on this site and they haven't gotten around to changing that. I actually way prefer the way the Judge calculates ...
