(Or maybe I'm confused and you did actually mean top 16?) | ||

(Or maybe I'm confused and you did actually mean top 16?) It means they were eliminated at that place. So if it says 16th place it means they lost in the round of 16 in that instance. | ||

But seriously, this is really cool. Nice to see the chances from the TL article have some numbers to them now | ||

Quick questions: -Did you use ELO or winrates? -Did you use matchup specific ELO (or winrates) or just general ELO (or winrates)? -If you used ELO, did you use the uncertainties quoted by Aligulac? -If so, what does the uncertainty look like for 300000 runs? I'm just curious, it should be really small. Besides the Aligulac uncertainties are very fishy. Example: ELO 1871 ± 81 for Taeja at 1182 games vs 1833 ± 89 for sOs at 247 games. Low number of games + consistent results ~ High number of games + inconsistent results. I get it, but I don't like it. Anyway, good work, really interesting stuff. | ||

Using tools as http://www.r-project.org/ that is free will give you to tools to maybe create a better simulation . Using a logistical model to work with this kind of data might work better but not sure about that (http://en.wikipedia.org/wiki/Logistic_regression). For now you should just add a similar response from lolfail9001 and state what those cases are “Aligulac just provides CHANCES for player to advance from group that he uses in his simulation to calculate chances of player advancing or not in certain cases.” It’s still not 100% correct way of saying it but people would probably just be confused if you tried to explain that the chance from Aligulac ranking is a estimation of what the chance can be and not the actual chance the player that is then used in a simulation to predict what the actual chance could be to qualify to Blizcon . The bottom line is that there is no wrong or right as long as you state the assumption the model is based on and the reasoning behind the decision you made(for instance why using Aligulac ranking as factor and not win ratio ect ). This is the only thing I would actually tell you that needs to be done better. PS:Sry if i sounded critical is still a nice contribution and well done work Why would you even write all the posts? I do understand the constructive criticism but hey... You are now offending the intelligence of all the people who read it and ENJOY IT. For one thing I work with stats and models for living and still it wouldn't come to my mind to criticize the work done. | ||

I use the aligulac rating which is similar to Elo. Currently I'm just using the general aligulac ratings and not doing it matchup specific, but I definitely plan to soon I am not currently using the uncertainties Thanks! | ||

I don't understand how ELO is related to this at all. Is Glicko based on ELO, or am I missing something else here? Aligulac rankings seem pretty good imo. Are there any better alternatives? I really enjoyed scrolling through the results of this simulation! And unlike some of the other posters, I think the model is appropriately complex! :-) | ||

I did say sry realising the posts i wrote was a bit to critical and to some extent unnecessary. As for why? the same reason you posting a critic on someone opinion .Just to clarify the work is good and I am just over critical. | ||

It takes about 40 minutes to run it with 300,000 samples like in the OP. I could optimize it to make it faster, but I haven't spent the time to do it and don't really need it to be faster anyways. | ||

This list could be updated (as you like) and have the, uh, I don't know, the 4 closest to take a spot as well or something. Would be cool to see how this top 20 will develop. Thanks. I'm not sure I understand what your suggestion is though. Could you maybe elaborate? Also Blizzcon is 16 players not 20. | ||
