How are the probability calculations for the american presidential election made?
It obviously cannot be calculated theoretically and it also cannot be calculated experimentally (i think), because it's a single experiment that has never happened and that will never happen again.
I'm a Statistics undergrad and i'm reaasonably fascinated about how these probabilities are calculated.
Spamming these top-tier Trump videos which were made before the election so that it will be safe for YOU to share with normies. This is a reaction to the pussyleaks video and aren't meant to be a redpill as much as a way for YOU to soften Trump's image to women and introduce the real Trump. SHARE THIS AND MAGA!
> NEVER EVER GIVE UP!!! > MAKE AMERICA GREAT AGAIN!!! > TRUMP 2016!!!!!!
Jacob Long
they're not calculated in an honest fashion. Many of these polls contain wording bias and an oversampling of Democrats
Nolan King
wow, he's back up to the 20s
Juan Moore
There's s comprehensive methodological summary on the same page where you got that image. A first year stats major should be able to follow along.
Cameron Brooks
>now under 80% fucking kek
Jonathan Williams
First of all, you need to realize that 90% of analysis are wrong because pollsters have no idea what they are doing and are making unreasonable assumptions. Got it? Ok.
So you take each poll in each state. You're obviously not polling every single person who would have voted there's some margin of error. What's that margin? Well, what are the odds that the people you randomly polled happen to really like Trump? Do some bayesian math, and you get a standard deviation around your results.
Calculate the probability distribution for a win in each state, sum them up, weight by electoral votes and you've got a relatively bad guess.

Clinton. Due to rigging she will win key counties in key states.
Jaxson Thompson
Vegas fag here, I'm starting to think we'll stay bule. I can't voice my opinion because both at my work and uni it's the same buzzwords tossed around about Trump. Unless the silent majority is real here I don't see how Trump can win Nevada
Brandon Rogers
>Hillary is sub 90%
GET READY TO MAGA BOYS
Blake Perez
Literally at the bottom of 538's forecasts they have a link to how they do it.
Why is Florida blue? Isn't he doing very well there in early voting? I've heard he's doing much better than the republicans usually do
I can't see Ohio going for Hillary either
Henry Powell
Step 1) Decide who you want to win Step 2) Mangle the statistics until your preferred candidate has a huge lead
Oliver White
Ive been screencapping posts like this. Im going to post a collage on post-election day. Just like I did for R-Money. Just like I did on Sup Forums For McPlane
Elijah Torres
He just said at the rally they are leading 4 points in florida
Zachary Bell
Its blue because Nate accepts +12D sampled polls the same as he accepts a +4D poll
Austin Long
And if Trump wins?
Luis Morgan
Trump just said at his rally
>WINNING FLORIDA, NORTH CAROLINA, IOWA, OHIO
ABSOLUTE MADMAN!!
Adam Morales
I've started my screencaps too. Look at my first one. The 9th is going to be glorious.
Carter Cox
Trump is doing good in FL but he's winning because Hillary can't seem to break over 160k votes over him that are needed to even break even. He is, that's not a lie.
Brody Price
Odds at predictit are traded with money. Money trading is the only sensible way to determine odds. People usually do not want to lose money, so they try to objectively analyze odds.
Lucas Carter
REMINDER THAT BREXIT ONLY HAD A 3.4% CHANCE OF WINNING
Ryder Thomas
Top KEK. Consider yourself collaged
Sebastian Morales
Trump Landslide.
Put in the collage now, even though you are going to delete it on the 8th.
Evan Robinson
55-45 Florida for Trump.
Isaiah Cruz
A lot of big money was put on Remain and smaller bets on Brexit. Betting odds aren't indicative. Now really, what happens if he wins? Would you die?
Christian Allen
Some cuck takes a lot of money from a particular group and shits numbers out his ass.
Bout it.
Juan Jackson
Lol. Most accurate summary I've ever heard.
Ryder Richardson
>A lot of big money was put on Remain and smaller bets on Brexit. Betting odds aren't indicative.
Doesn't work for predictit. There is a 1000 dollar limit per person per trading question. You cannot manipulate it except by creating many fake accounts just to manipulate the odds. Not sure why anyone would do that, as predictit isn't reported much on.
Brandon Baker
His message has to be: >if you vote, we win. >your vote is the most valuable thing in this country, and with it you can change the world. >double check to make sure they don't steal it from you and let's all take back the white house!
Samuel Parker
>What if he wins
Mostly nothing. Worst case scenario is he's a slighty offensive version of W Bush. No matter the outcome of the election, my life will be fine.
Gabriel Ward
Good to hear, reckon it's likely he'll win PA? Seems pretty much like a must win
Logan Butler
You're assuming what anyone not ctr on this board will tell you is not true, which is that nate formaline is not a complete hack.
I haven't seen him explain his """adjustments""" so I presume they're just his wittle feelies
Oliver Turner
What if it actually happens?
Ryan Morris
Any chance Trumps odds go down again? I've been waiting to place another bet, but idk if there will be a better time than now.
Hudson Jones
Good to know. PA will be hard to flip but definitely possible. Would be easier if Trump manages to flip NV, NH and ME though.
Robert Evans
yet they go to vegas and blow their savings all the time Little hint to everyone too that was brought up in brexit and somehow isnt now, the bookies payout rates are also based on how many bets were made for any particular candidate if everyone is betting on hillary, whether they support her or not, the payout will be lower regardless of actual odds so they still make money.
Jordan Baker
Most likely not.
Noah Garcia
His adjustments are literally wishful thinking.
Thomas Brown
Damn nigga you retarded
John Flores

Damn nigga, you're poor.

Nope i capped your posts, will post when trump wins then youll feel irritated
Ill post them around this time make surr youre on here
James Nelson

Joseph Hernandez
Challenge accepted nigger
Austin Watson
I have this capped for a potential Trump victory
Lucas Reed
Oh, he has no chance, but do you still get money when he loses?
Jackson Collins
>Indiana only around 50 >Texas only around 50 Sure fucking thing Shillary.
Robert Bell
>when trump wins Top kek m8 He'd have to take Florida, Ohio, North Carolina AND Pennsylvania to win. He doesn't stand a chance, especially in Pennsylvania.
Ayden Sullivan
The assumptions used matter A LOT, and there's no way to get better assumptions about a future event. I mean you could continue to ASSUME that the future event will play out similarly, or maybe even identically to past events of that nature. But shit, I mean you're even making raw assumptions about SAMPLE SIZE and shit. I mean, the first Stats class you ever have states that you start every analysis by defining the sample, and that's the most important assumption that you make.
TL;DR There isn't a way to be terribly accurate with demographic assumptions about voter turnout.
I would say the uncertainty in the results of the polls are much higher than what's reported, because their uncertainties are CALCULATED, based on quantifiable aspects of their analysis. But there is NOT a number to factor into uncertainty for assumptions like enthusiasm and "willingness to register for a major party." I mean, you could qualify it, but it's a representative number, not a measured number. Sort of like the Pain Scale doesn't have any units. Because it's subjective/made-up bullshit.
Wyatt Hill
>putting NV, OH, IA, and FL all in blue >States where Trump is literally winning right now
God who invited fucking Brazil to talk about American politics?
Anthony Gutierrez
Are those bots posting those tweets? It's word for word..
Ethan Phillips
Sometimes the pollsters just aren't aware of what is happening.
The reason why Clinton was +20 in the Michigan primaries was because the pollsters did not realize that Sanders was popular with young voters.
yes i'm sure that if trump loses all his supporters will come here just to get humiliated by shills and shitskins
Robert Cook
You're a statistics undergrad and you're asking fucking Sup Forums?
What the fuck man?
Caleb Bell
Okay, i read the 538 user guide, and it's bullshit.
You can read it and still not understand how the calculations are done, because what's in there isn't a complete, detailed methodology. There is too much stuff being simply referenced, but not shown/detailed.
I want to see the math, the data, and the program, but specially the math.
Easton White
I asked elsewhere but it's hard to get answers.
Here i get answers, although most of them are low quality or not even answers.
It's not open source. You should not expect them to show you everything. Quite the opposite, indeed. Still, they do say a lot. If you know what they are talking about, you can replicate their results.
Jack Gomez
>doesn't know the difference between editorials and polls
the last fucking article even explains exactly that
Jonathan Myers
Thanks. Will check it at some other time.
Nathan Ward
>currently wiining all those states, even if you presume he does get the proportion of independents even the (((polls))) says he has.
Josiah Ramirez

Kevin Miller
except for cases like predicit it where most of the money betting is based on the odds given by the polls.
Oliver Anderson
Doesn't, fuck you shitty android, I am going back to my blackberry.
Ethan Collins
What the fuck are you learning if you can't comprehend this.
You take representative polls, have some kind of error and a certain distribution around your mean value. From there you just simulate the election.
Bentley Murphy
Reminder that this is absolutely not true.
Blake Young
yes
Matthew Barnes
very few people actually understand what probability is
Jace Sanders
>didnt even read the file name
Brayden Smith
what's the website, I want to place a bet on Trump.
Nathaniel Torres
Sup Forums really needs to do more, less than 2 weeks now until the election
Henry Hughes
Bovada is the only one that takes Americans.
Aiden Mitchell
They receive the correct numbers by mail from CTR.
Luke Gray
Well exactly. So even if a poll is as honest and skillfully done as possible, there's no way to have all the information, and so the result is always, at best, a guess, and at worst, an advertisement.
Eli Reyes
if you did statistical modeling in any class you'd know it's a bunch of bullshit filled with loads of assumptions. stop accepting what nate silver says as gospel.
Personally I think both the betting markets and polls are correct in a sense.
If it was a regular election or if you expected the same turnout as in 2008 then for sure Hillary would be a massive favorite.
The problem is that this is not a typical election. This is the exact opposite of that.
Let's not forget Trump holds the record for most votes ever by a Republican in the primaries. And that was also in the biggest field of candidates in the history of the GOP.
Just putting those two facts together is mindblowing and a glimpse of what sort of popular support Trump has.
We're talking people who have never voted in their lives or who haven't voted for 30 years. Then there's also the shy Trump voter who can't express his opinion for fear of social shaming and marginalization.
The problem is there is no scientific way for polling agencies to account for this. Their options are to take vague guesses and expose themselves to risks or just play it safe and use old turnout data. They chose to play it safe.
There will for sure be a huge turnout for Trump. I don't know if it will be big enough to win but it will be a close race. Way closer than polls or betting markets have it.
If you ever plan on betting on Trump now's the time to do it, because his odds are only going to shorten as the election approaches.
Adam Nelson
Shit odds, what site is that?
Leo Jenkins
Weird how suddenly Trump is doing well in the polls days before the election.
It's as if the polls are rigged and the media is trying to save their reputation post-election when people find out that Trump actually had a better chance than what the polls said.
Hunter Foster
I'm a burger so I got stuck with Bovada. I placed that bet before the first debate, but Bovada matched that deposit, so I really only had to put up 250 dollars.
Bovada still matches deposits but only 50% of them. Their odds are a bit worse than the other sits, but better than most when you consider the matching deposit.
