But the only thing varying is a scalar, is the point. The fact that you can write it as a vector is irrelevant.

I have no idea if the author describes "friedman's thermostat" correctly, but to say that Economists are unaware of the phenomenon he describes is beyond absurd (disclosure: I'm an Economist!). There's another way to find the relationship b

There are lots of ways that artists could hypothetically be compensated and things will probably change a lot over the next 5-10 years. Right now, though, pretend buying overpriced t-shirts is one way to get money to musicians without goin

fastmail.fm lets you set up wildcard mx records -- so if your email is user@example.com, you can get email at company1@user.example.doc, company2@user.example.com, etc. instead of user+company1@example.com. I imagine other email providers

Bullshit. A compelling counterexample to "all these graphs that keep getting published" is far and away the best way to establish your scientific reputation, get a job, get money from the NSF, etc.

For cooking: I'd say 'pinch' or 'dash' and then clarify if the person asked for clarification. If he or she looks puzzled, I'll offer the clarification unsolicited and as naturally as possible. When I cook pancakes on the weekend with my

Reread my last paragraph -- you misunderstand my position (phrased for maximal irony). I care very much if my students or (hypothetical) employees misuse terminology. But the best way by far to communicate that a value changed from 10% to

Look, this isn't a matter of "agreeing on the terminology." I know and use the correct terminology, but I don't get bent out of shape if the person I'm talking to doesn't know it. Especially when their mistake is obvious and I can correct

I "rely" on the person saying that it went from 10% to 12%. I'll refer to such a change as a 2 percentage point change, but if the other person calls it the wrong thing, I don't really care. I'd be much more concerned about someone getting

It's a change of two "percentage points," not 2%. With the right vocabulary, there's no ambiguity.

This isn't quite what you asked for, but I've run into problems where the distinction between scalars and 1x1 matrices was important. iirc, something like crossprod(y, crossprod(A, y)) * V where A was nxn, y was nx1, and V was an a

Depends on the data sets you want to work with. For straight-up linear regression, with a heavy emphasis on observational data appropriate for microeconometrics, "Introductory Econometrics: A Modern Approach" by Jeff Wooldridge is absolute

Sure, but your original point seemed to be that any small degree of progress on a Siri variant would be more important than any large degree of progress on a news aggregator. My only point is that the magnitude of the progress matters, and

Sorry about your experience. Unfortunately, grad school in Economics is a bad environment for positive feedback even if everything is on track.

A really good news aggregation/management site would help me out a lot more than a marginally better Siri. I waste a lot of time on the news and miss a lot of stuff.

That looks nice; part of the advantage of beamer, though, is that the equations and (especially) inline variables are automatically positioned correctly and consistently -- it looks like that might not be the case for LaTeXiT.

This won't apply to most people, but if your talk involves any math at all , use LaTeX + Beamer (www.math.binghamton.edu/erik/beameruserguide.pdf) to prepare pdfs of your slides. They will look much better. The beamer user-guide also has

This might be slightly off-topic, but are DataFrames intended to be similar to R's data.frame, where the contents of the entire table are loaded into memory and operated on all at once, or more like SQL with the possibility of aggregate fun
