What would be the justification for removing the discounting term for subsequent goals in the Elo model he mentions?

Silver mentions that it was the lopsidedness of the score that made the game so surprising, and that the Elo model discounts increasingly lopsided games. As a consequence, this game would not be the "most surprising" game in the history of the world cup. Thus he removes the discounting term, re-runs the model, and poof this is now the most surprising game in World Cup history.

That just smacks of attempting to fit a model to one's intuitions. Was it any more "shocking" that Germany won 7-1 than that they were up 5-0 at halftime? I would presume that the "lopsidedness" discount is intended precisely to address the idea that once a team is winning by an overwhelming score the subsequent goals aren't really that surprising.

Really, though, a measure of "shockingness", at least as described in this piece, suggests more about what the Elo model cannot capture than it does about the subjective way that any one game was perceived.
We could, but I'm trying to take an 'all other factors being equal' approach so as to minimize the number of assumptions required, and so considered the second amendment issues in terms of how they're currently interpreted rather than how that interpretation might change.

I feel that this is a result of many Haskell users (and, likely, the writer of that example) being more familiar with mathematical notation than the average programmer. With the correct unicode replacements set up in your environment, it's sometimes hard to remember that you're actually writing code! (IHaskell has these by default)

For a declarative language like haskell, mathematics is arguably a much saner inspiration for notation than C/C++. I recommend avoiding any temptations to relate the two. When you see "return" or "class" in the code, treat it as a completely new idea.

I imagine the discount on a lopsided game is because the teams stop really playing. After 3 goals or so it's generally a done deal. So you start to see players pulled, playing very differently (conservatively).
Is statistical analysis useless for soccer? No - Australia was unlikely to win the world cup.

Is the 538 model a good enough one? No - when we have two events it thinks are extremely unlikely (this and Netherlands-Spain 5-1), we should suspect that there's something going on it's not capturing.

From the report:

"Here we use neuroimaging and voxel-based morphometry to examine brain gray matter in incarcerated male adolescents who committed homicide (n = 20) compared with incarcerated offenders who did not commit homicide (n = 135). Two additional control groups were used to understand further the nature of gray matter differences: incarcerated offenders who did not commit homicide matched on important demographic and psychometric variables (n = 20) and healthy participants from the community (n = 21)."

Perhaps someone with expertise can comment on a couple of points:

1) Am I correct that this research is preliminary, given the number of subjects involved? It seems too preliminary to even report on HN (to answer my own question), but maybe I don't understand it well enough.

2) Is there reason to believe that the brain differences caused the homicide, rather than believe that committing homicide and getting incarcerated, two very traumatic events, caused changes to their brains? Or that something very traumatic caused them both the crime and the brain changes?

Thanks for mentioning Khaybar. Anybody looking for context can start here:

http://www.thereligionofpeace.com/muhammad/myths-mu-home.htm

"Understand that it is the Hadith (traditions), Sira (biography of Muhammad) and the Qur'an together that provide the true Islamic counterpart to the Christian Bible and Jewish Torah."

http://www.thereligionofpeace.com/muhammad/myths-mu-rape.htm

"It is against Islam to rape Muslim women, but Muhammad actually encouraged the rape of others captured in battle. This hadith provides the context for the Qur’anic verse (4:24):

The Apostle of Allah (may peace be upon him) sent a military expedition to Awtas on the occasion of the battle of Hunain. They met their enemy and fought with them. They defeated them and took them captives.
Some of the Companions of the Apostle of Allah (may peace be upon him) were reluctant to have intercourse with the female captives in the presence of their husbands who were unbelievers. So Allah, the Exalted, sent down the Qur’anic verse: (Sura 4:24) "And all married women (are forbidden) unto you save those (captives) whom your right hands possess." (Abu Dawud 2150, also Muslim 3433)

Actually, as the hadith indicates, it wasn't Muhammad, but "Allah the Exalted" who told the men to rape the women in front of their husbands - which is all the more reason not to think of Islam as being the same as other religions."

"There are several other episodes in which Muhammad is offered the clear opportunity to disavow raping women - yet he instead offers advice on how to proceed. In one case, his men were reluctant to devalue their new slaves for later resale by getting them pregnant. Muhammad was asked about coitus interruptus in particular:

"O Allah's Apostle! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interruptus?" The Prophet said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.” (Bukhari 34:432)
As indicated, the prophet of Islam did not mind his men raping the women, provided they ejaculated within the bodies of their victims."

The references are to the actual "holy texts" of Islam and can be easily checked online. (Instead of downvoting, please point to anything that isn't true.)

(And just that it doesn't appear that I'm cherry picking only Hadith, Sira and Quran, for the list of the killings of the God as written in the Bible, refer to:

http://dwindlinginunbelief.blogspot.co.at/2010/04/drunk-with...

Also with the exact references. Do check the original texts yourself!)
>How do you punish someone who unwillingly commits atrocities

I look at justice more as a "confinement of the criminal behavior" than "punishment of the criminal". Viewed that way, I don't see a dilemma in being able to better identify the behavior, especially if the confinement is done after a criminal act.
No, this match had nothing to do with Neymar missing, and everything to do with Thiago Silva missing.

Neymar wouldn't have marked Muller for the first goal. Nor would he have been at the back to clean up the second fuck up, and the many fuck ups thereafter.

Thiago Silva is an excellent defender who organizes his defense to ensure proper defensive shape. In his absence, David Luiz was in charge of the same, and he isn't a particularly great defender to begin with (decent attacker, sure, but not a good defender).

Further, football resists statistical analysis, unlike most American sports, because momentum plays a HUGE part. Upsets are a common phenomenon in football. Small teams beat the big fish ALL the time.
To be honest: This would turn me off even more than the current example which is also hard to read/understand as a non Haskell programmer.
The fibonacci example in another comment in this thread however is very easy to understand and would fit much better.
This is great advice. Just today I had a similar issue. I wrote some code a long time ago, and a new coworker who started about a month ago comes up to me and proposes an alternate solution. He asked why we didn't do it this way instead of the way we were doing it now. In his mind, his solution made perfect sense.

I knew I was right, and I knew my solution was the best solution, because I'd spent months thinking of all the possible ways to solve the problem, and this was the best of them all.

But the point is that he asked, and the point is that I had to revisit that decision. I considered what he said, and I explained my rationale for going with my solution. By the time I was done, he was nodding along and saying "Yeah, that makes perfect sense."

I think it's okay to be right and to know you're right, but if someone questions you, or if a test fails, or if conversions go down, you should be willing to stop and re-examine your assumptions, and if necessary, explain them again.

I'm very glad my coworker brought his ideas to me, because it validates that my solution was, in fact, correct. And if my solution hadn't been the best choice, he would have brought a better solution. So in the end, it's a win-win...

Assuming you're wrong at first blush is almost always the right move. It lets you consider alternate solutions, and hopefully rebuild your defense of your current solution. If it still holds up, you're good. If not, your new assumption is right (that you're wrong).

I think I have a headache now.

I also have a similar rule, but from a slightly different perspective. I credit it as one of the reasons for me being as successful at my company as I am.

When someone comes to me and says there is a problem with the app, I assume it's my fault. I assume it's a code problem. I rule out any responsibility on my part (or that of my team) before I go back to the complainer and ask them for more information. I never, ever, ever say "it works for me."

Remember: people don't complain about things that work. Even if it's their fault, even if they screwed something up, even if it's not your code that's broken, something isn't working for them. If it's not working for them, then it's up to you to figure out why. It may be that your instructions were unclear, or maybe it's a client-side issue (like an ad-blocker) that you can't reproduce. Or maybe your customer really is a moron.

But before I ever go back to someone and tell them I'm good, I make sure all my ducks are in a row. The last thing I want is to belittle someone else's problem because I think I'm awesome.

I mean at the broad level, sure stats applies. But even so, not many would have predicted Spain going out at the group stages, or Holland making it to the semis.

Football is a highly unpredictable sport because individual contributions can completely change the course of a match. All it takes for a minnow to beat a big team is some organized defending and a lucky goal, like Switzerland vs Spain past WC.

In a sport where the margins of victory are small, it is difficult to apply statistical analysis correctly.

It isn't quite that black and white. Genetics generally predispose you to things, but they don't make you do things. I could be proven wrong eventually, but I don't believe that it's pre-determined that you will commit X crime.

Part of equality is everyone is held to the same standard. So even if it is biologically harder for you to resist falling into a murderous rage, you are still just as responsible if you do.

I think that even the hedge fund stories have more to them than meets the eye for a casual observer. I have a classmate who works at Bridgewater, and has since graduation (well, graduation plus the six months of unemployment it took to find a job). He got there by e-mailing everybody in the Amherst alumni directory who worked in finance and asking if they'd give him a job, and an alum at Bridgewater was the only person who responded affirmatively. Now, he ultimately got the job through the alumni network, which is a tool that wouldn't be available to someone who didn't go to school - but his path was still full of rejection, stress, and closed doors.

I suspect that college does help skew peoples reactions toward you favorably, but that the ability to hustle ultimately matters more to your long-term success. Then the question is whether having that lifetime skew effect is worth the $100K+ and 4 years of opportunity cost. My personal feeling is that it probably is if a.) you get into an Ivy League or "brand name" college or b.) you come from a lower-class background and your parents don't have a network or much cultural capital. But for most middle-class kids going to a second-tier college, the opportunities it opens up are mediocre, and you are far better off putting the $100K+ and 4 years to work distinguishing yourself in some other way.
I think he meant average in the sense of generality, not in the sense of the average function.

I'm not saying they're corrupt, of course, but I do find that more empirically likely.

Perhaps, or maybe the right data just isn't tracked / accessible yet.

Basketball is an instructive example --- as recently as 10-15 years ago, it was thought that this game couldn't be quantified/predicted nearly as well as baseball, that it had a lot of the same fluid properties of soccer and (US) football. Fast forward and a lot of work has been done to push basketball much closer to the baseball-side of the spectrum. Whose to say whether or not taking detailed data of every movement of every player in a soccer match might yield similar breakthroughs.
I don't think it conflicts with it, but I believe the correct explanation has to do more with tiny changes producing big ramifications than with being deterministic or not.

This article more or less is my understanding of user acquisition, but I've never understood where Atlassian fits in this model. I'm sure that today they have mostly switched to the "Sales" model. (despite claiming to not have "salespeople", I understand they just call the role something else)

I don't think it's always been that way for Atlassian, though. They started out as just a few people and certainly earlier on it seems they didn't do much sales.
