All that will do is cause a million loud, uninformed people to make silly counterarguments. He's obviously using some fairly arcane statistical methods that the average dota player won't understand. Of course, doing something complicated doesn't automatically make him correct, but it does mean that 99.9% of his audience isn't qualified to have an opinion based on the methodology, so releasing it is irrelevant for most of us.
What we are qualified to have an opinion on is whether it makes sense in terms of results. If he really wants to prove himself, he should walk through some cases where he demonstrates his predictions and outcomes, and make sure the cases include some smurfs and high-disparity stacks. That's the kind of information that a layman audience can actually process.
Personally I think this whole thing is a scam to get Yango to blow his 20k by banning everyone for surreptitiously discussing ranked ladders. Yango is cheating, he has created a new account despite that it's forbidden. It's called notyango.
That can't be Yango. Its there there in the name!

Maybe his 20k post can be a ban appeal :p

What if his 20k post is in the LoL subforum instead of ours, how devastating would that be?!?

Why are the last infinite pages full of spam from some guy who claims to have a statistics background defending a rating which fluctuates SO WILDLY it can't honestly claim any confidence interval at all?

That's my guess anyway.

Comparing against others wont give you anything good. And the site is still in massive beta from the looks of it so your DSR number might change just for the worst just from patching.
The developer seems decent so in the future it might be useful but all of these different rating numbers is usually worthless for self improvement its dangerous to get caught in pointless ego boosting. If people actually want to improve their play they should watch their own replays and analyze as well as watching specific heroes/roles played by the best(pros) and try to emulate. Most important is probably to try to find people to play with/ against who is already better then you.
Not sure why I went on this rant but Im getting tired of this DSR/Dotabuff mania going on. Of course you can compare it to other people. It's also the whole basis of why DSR can predict the winner of a game.

Can this be taken as a legit base line of your skill level? Not like a true indicator but more of where u stand in the dota ladder?
Though I wonder how they actually calculated your DSR. What is the difference between this and Valve internal rating? DSR's gone through 3 or so iterations where they adjust the algorithms to produce new and exciting numbers that may or may not mean a damn thing to anyone at all. They're not a good indicator of skill. By the site's only admission, it is only able to predict the winner of any given game correctly 65% of the time. Seeing as that's only 15% better than a blind guess over many iterations, I'd say it is still pretty damn inaccurate. People who don't have a background in statistics need to stop saying things like this. 65% prediction accuracy over a large sample is RIDICULOUS and if that 65% is proven to be true it is clearly evidence of DSR's accuracy. It would be a statistical fact except people who don't study stats can't be convinced because they can't understand the proof. I dont think any of that matters when most of the player profile is set to be hidden by default. Meanwhile, Player number 34176943 DSR is: 1275 This player has a Pro DSR score (top 0,5%). >_> and my smurf now is 460. I am entertained enough by now, that will be the last time i visit the site. and i fcking respect the people behind dotabuff now. http://www.reddit.com/r/DotA2/comments/1s4ezx/mydotaskillcom_and_why_it_should_be_ignored/cdtubbcHidden profiles shouldn't matter. Yes it does very much so matters, unless some people just wanted a number to say something meaningless about their skill/ranking then it shouldn't matter to them i guess (or anything matters to them in that case, hence the ridiculous ranking from the website). You can talk about fancy stats techniques etc but in the end of day I hope people know that the site is a joke lol (a bigger joke than DBR if you must, and i actually respect the stats guys behind dotabuff now because they actually have the self-respect and morale as some statisticians. say 1000 out of 100000 players are actual top class player, ill give you 800 of them have the profile opened for public because high level players surely care about their ranking (obviously i am being very generous here, go search dendi pub games you will almost always find 1-5 players that are anonymous), so in this case there are 200 top class players that will never be included in the stats results, ie the ranking of these 800 players will forever be not accurate because we know there are differences between top top top top class players and top class players. and then lets say 40000 out of the remaining 99000 players have made their profile public, that's a very generous number because that would mean almost 40% of the players are showing their profile. I think I'll stop here now because if you still think that DSR means anything then there is nothing more i say can persuade you to think otherwise lol. p/s: i am guessing that DSR is using somesort of 'curve fitting' model to 'predict' people rankings but in this case of dota2 player pool, it wont be a meaningful curve. Holy fuck. You're trying to argue against something that already happens in real life. Let me see if I can break this down really simply for you with a braindead example. When your country (I'm assuming the UK does these) conducts a census of the population, they do not collect data from every single person living in the UK. They collect an INCOMPLETE data set. Yet they can still draw conclusions from that data set like who the expect certain demographics to vote for, if there is mass migration from rural to urban districts, etc. Here's another example because of how adamantly you want to argue on a topic with which you clearly have no academic or professional experience. When Nate Silver perfectly predicted the 9 swing states for the US 2012 election, I PROMISE YOU he did not collect data from every single voter in those states. Drawing accurate conclusions from incomplete data is done ubiquitously all over the world in many different fields. DOTA2 is just one of them. You still dont get it do you. I'll put it in another angle to read my post: 'DSR is for some people who just wanted a number to say something about their skill/ranking'. Of course it depends on how well one is convinced from that website but in reality that 'something' can be pretty meaningless. How meaningless it can be? nobody knows. If the creator of the website said the accuracy is X% then he is pulling that out from his ass, he CANNOT know that X%. I am not even talking about the absolute accuracy here, i am talking about a convincing ranking. The fact that the website is telling people to stop stacking with noob friends in order to get a higher ranking means that they cant be sure of your skill level if you stacked. Valve who has all the real stats couldn't figure out a good MM to work (they will need to make a good ranking system behind to do so) and some magical website somehow capable to achieve that? Funny because i am doing some population-based cohort study of some patients of a city so clearly I don't know anything about statistics.
Statistically you can know something with xx% confidence. That's just a fact.
If you're skeptical about DSR that's one thing, but when you make arguments like "you can't draw conclusions from incomplete data sets" or "he must be pulling a prediction rate out of his ass because you cannot know the X%", it really is evidence you have no idea what you're talking about.

And being aggressively insulting to people more or less at random.  Instead of being a passive aggressive beta like what you've been doing? First of all, calm down. Second, you want me to be more direct? Fine by me. Remember, you're the one who decided to jump on me with your inane and bloody obvious comment that "what the numbers mean has changed!" Then you decided to follow it up with a flippant comment about "oh you've got to have soloQ games that aren't in LP" which frankly I find hillariously presumptive and, again, bloody obvious. Not to mention your high-handed and insulting responses with regard to anyone in here who has actually attempted to ask you a question or, god forbid, actually make a point against it. You're arrogant, aggressive and even being nasty to those genuinely curious. No, not everyone on here has statistical experience to understand arguments in favour of the system (I do as a matter of fact, I'm a research scientist, but that's besides the point); but I'm willing to bet a good proportion of people on here are smart, educated people with the CAPABILITY to understand. However the way you're treating people is convincing nobody of anything. Sort out your attitude and people may start to actually listen.
Point to a comment that I've responded to where someone has been "genuinely curious". It's just people who dismiss it out of hand and double down on their views after a response.
You're going to add those little smileys at the end of a sentence calling me out and talk shit about *my* attitude? Get real.

That's not how you use a confidence interval.

The discussion about DSR has made me care less about it than before I knew it existed. It does not sound like an accurate metric of anything. Plus the people who are really into it are not making it more appealing.
