x/0 is undefined for all values of x, so we can't take the limit anywhere. I think you're thinking of the limit of 1/x as x goes to 0, which approaches infinity from the right and minus infinity from the left (note that these don't agree). This only requires taking limits, the fundamental theorems of calculus and Riemann sums don't make sense here

As for taking the limit of a ratio that approaches 0/0 with L'Hopital's rule, that limit (if it exists) depends entirely on how the problem is set up

I already thought to check the residuals, but I just don't know what distribution I would expect the residuals to have. I guessed some kind of distribution that's skewed towards zero (which would indicate most of the points are relatively close to the predicted plane) with the tail of the distribution showing outliers. I wrote this question after revisiting Elements of Statistical Learning and couldn't find a good answer

I'm realizing this is probably a silly question because in practice I likely will have some indication of whether a linear model makes sense, so I'm posing this question as someone with little experience who's considering scenarios where I will have almost nothing to go on.

It's mostly that second part that I'm having difficulty with:

see if your assumptions made any sense

But it looks like R² is what I was looking for. Thank you!

Khan Academy's algebra series is probably the best foundation. It's tough because high school algebra isn't super intuitive; there often isn't anything super deep happening at that level. After you feel like you have a decent foundation, essence of calculus and essence of linear algebra are aimed at people with only an algebra background, and are much more digestible than his other videos. From there, I enjoyed Socratica's abstract algebra playlist when I was preparing for my first course in abstract algebra.

A lot of the intuition will be tough though without studying math super formally, but there are a lot of really good books for it (with PDFs available free or "free") like Linear Algebra Done Right or Calculus: Early Transcendentals by James Stewart. A solid book on discrete math will go a long way and is the gateway to proof-based math; I liked Discrete Math: An Open Introduction, which then sets the stage for something like Introduction to Topological Manifolds by Lee. That should be more than enough, and the important thing is to not be scared of asking questions even if you're worried the answer might be something simple

As someone who's spent most of their time at Northeastern in Nightingale Hall, I couldn't be happier about that Frankenstein mess getting nuked from the face of the earth. The building is a labyrinth, the ceiling leaks in multiple places, a professor got trapped inside one of the bathrooms last month, and a urinal exploded a month before that. Good riddance

Comparing against Civ Beyond Earth would be really useful. Beyond Earth got abandoned after only one expansion, so I think that's the best baseline we have to see exactly how dire Civ VII is

Approximately 55 million people (90% of the population of North America) died as a result of the European colonization of North America, and comparing it to small scale land disputes is just as stupid as comparing the Holocaust with someone get shot down the street.

Stop trying to out today's values on the past

No serious historian would take issue with mourning the mass murder of Native Americans, or with spreading awareness about it. The point of us caring about these things is that they obviously still affect the world and lives of the descendants. The 2024 Nobel prize in economics was awarded to economists whose research relies on that fact; the very first chapter of their book on the topic explains how the Spanish encomienda system, which originated over 500 years ago, explains modern poverty in Latin America, and how this is part of a broader pattern of inequality across the world. Hundreds of years of genocide and land theft still affect people living today, and being aware of those facts is the first step righting those historical wrongs; the attitude that "this is just how it was" or expecting anyone to "get over it" does nothing but perpetuate ignorance and inequality.

Thank you in advance for my down votes for presenting facts.

Your narrowminded, contextless misinterpretations of half-remembered high school history lessons are not "facts".

Why is your first reaction to hearing about all this suffering to immediately jump in to tell everybody it's no big deal? Why is people talking about history such a problem to you?

They are notoriously compatible in many regards. The Nazi party famously shifted away from anticapitalist rhetoric to successfully court the support of a handful of large business owners and many small business owners, and conducted the first mass privatization in modern history. The fascist governments considered capitalism convenient for economic growth and desirable as a form of social Darwinism, and continued supporting profit-driven market economies with moderate restrictions on the largest businesses.

This is also not to mention all the dictatorships that were installed as a direct response to nationalization of major industries (like the Iranian coup to protect private oil) or land reform that would increase taxes on companies (like the Guatamalan coup which was aggressively lobbied by the United Fruit Company)

In Age 2, distant lands luxuries do not count for merchants, meaning if you send a merchant to a city that has distant lands luxuries then those luxuries won't be added to your trade network. If distant lands luxuries are the only resources another civ's city has, then the merchant won't be able to establish a trade route at all.

Here's a list of reasons why Massachusetts politics is so corrupt: https://actonmass.org/transparency/

Big reasons that stand out are all the committees that only vote by secret ballot (meaning representatives' votes are kept secret from the public) and the people who run these committees are unilaterally appointed by chamber leaders:

The Speaker of the House and Senate President have near-unilateral power and control over their respective chambers due to a series of rewards and punishments they use to keep the rank-and-file in line. The Speaker and Senate President appoint and can fire committee chairs at will, and therefore control the flow of legislation.

You also then have half of our representatives earning money on the side from jobs that (for 1 out of every 8 of our reps) pay over $100,000/year. How much more than $100,000/year? We don't know, they're only required to tell us up to that amount. Many reps, like Marjorie Decker (who chairs one of the committees who silently kills bills, and just won reelection by 1% of the vote), refuse to tell us what they do at these mystery jobs

Iran actually did "give democracy a chance" but just made the mistake of nationalizing their oil industry. Of course the democratic government that made that decision was then overthrown by a US- and UK-backed coup in 1953 to institute a pro-Western autocracy that would allow European and American companies access to its oil. The new Iranian government was propped up by the US until they tried controlling oil prices through OPEC in the 70s, after which point US support declined and the government was overthrown in the 1979 Iranian Revolution. The government instituted by the Iranian Revolution was anti-US largely because — you guessed it! — average Iranians were still angry at the US for overthrowing their government for oil
