What you've described is "poor judgment."

Fair enough. To the extent I do, I usually share business cards at the end of a conversation so pulling out the phone isn't really an interruption.

That is hugely misleading. It's only reasonable if the data are actually independent draws from a normal distribution. IRL, they're not.

It's very unusual to not cover hypothesis testing in an introduction to statistics class. The students are going to see "testing" again. The passage you quoted was about teaching from the book, not using it for self study.

A clear link to the LaTeX source file on github would solve a large part of the proofreading problem. Especially since the book is nominally licensed under the GNU FDL.

I haven't looked at it carefully, but it's hard to think of a setting where I'd want to teach from this book: it's aimed at stats 101 students, but uses python as the programming language (great language, but far beyond

That's what the absence of a CLA would achieve. Adding a CLA explicitly gives the company the option.

I use this template for handouts (with some changes: the default fonts drive me nuts so I use Charter). But that's mostly because I like having room to take notes in the margins, and I like the sidenotes. For anything I don't prin

Dude, take "Skateboard club at Georgia Tech" off your resume. Especially since it looks like you either quit or were kicked out of your role as founder and president after your first year!

I think "repeal economics" occurs at step 2.5, unless somehow customers can be forced to buy even more at the higher prices than they'd ordinarily want to. Step 3.5 is just sound business once you've got the customer bas

That may be true, but it's not mentioned in the article. Is there a good reference if anyone wants to read up on Frosty Pod Rot? edit: apparently it is mentioned in passing. oops.

A more accurate title might be: "world's biggest chocolate-maker tries to prepare customers for higher prices by disingenuously claiming that we will run out of a renewable resource."

These are pretty, but I put absolutely no faith in a "confidence band" implemented by anyone who doesn't feel a need to explain their formula. It's surprisingly difficult (serial correlation, for one thing.)

MIT's OCW is fantastic. It's not what I think most people have in mind when they talk about teaching themselves a subject over the internet (especially since many of the classes I'm familiar with have assigned textbooks and h

Teach yourself real analysis over the internet. There are people who can, but not nearly as many as can learn it in a decent undergraduate math class. I imagine the same is true for other difficult subjects.

I want to be clear up front that this isn't really a comment for you, but a more general comment for any students reading it. FWIW, I teach at a university, but this is just my own opinion and others might disagree. > My perspectiv

Some comments degrade the quality of the conversation. We might disagree about which ones, but surely we can agree about that, right? The obvious candidates are purely asshole comments, trolling comments, intentionally racist comments, etc.

It moves stupid comments down _faster_. If the comment's super stupid, that can be worthwhile.

You lose the ability to write step functions as g(y) = ∑ᵢ cᵢ × (y ∈ Aᵢ) which is useful when you define integrals and expectations: E g(Y) = ∫ g(y) f(y) dy = ∑ᵢ g(cᵢ) P(y ∈ Aᵢ) where Y is a random variable with density function f. Any integ

I think it still probably depends on whether it lowers the cost of car insurance, which probably varies state by state.

I read less negativity into the comment than that.

x ∈ (A ∩ B) = (x ∈ A) * (x ∈ B) if "x ∈ A" equals 1 when x is in the set A, 0 when x is not in the set A. Using "indicator functions" like this also gives you a nice formulation for probability and integration, etc. that

Check out the PyCall[1] and PyPlot[2] packages, then. Julia has pretty good integration with python. I've been pretty happy calling matplotlib from julia. (You probably already know about these packages, but just in case you didn'
