This looks like it's roughly at the level of Allan Gut's intermediate probability book ( https://www.amazon.com/Intermediate-Course-Probability-Sprin... ). There's a need for more exposition at that level, but

The database course I took covered that a bit. We used https://www.amazon.com/Database-Management-Systems-Raghu-Ram... . It's not the most up-to-date text (although it was when I was in school), but it's probably

A lot of machine learning people don't really understand study design or power or things like that. It's gotten a little better over the past decade or so, but this is an area where the field has a lot of room to improve.

Do you know a good introduction to adaptive/sequential designs? I'm looking for something along the lines of a textbook aimed at a graduate level seminar.

I'm just going to present the absolute basics of the topic. It'll be a high-level overview of something along the lines of chapters 1-4 of https://www.amazon.com/Analysis-Experiments-Chapman-Statisti... .

The big problem for Netflix was that their data was all from DVD rentals, but by the end of the contest, their business model was very streaming oriented. As you might imagine, people have beliefs about what they'll want to watch in a

People should be using more than one design, but that's not as commonly taught as it should be. I'm going to give a talk about that to my company's ML group in about a month, and hopefully that'll improve things where I

Black Scholes isn't a bad approximation for pricing short term call options that are either in-the-money or not too badly out of it. For anything else, the assumptions that go into it mean that it's wildly inappropriate. It need

The headline is certainly overblown, but there probably errors out there. The interesting question is where we should be looking for them. All of the major results in an undergraduate or introductory graduate textbook have been studied of

How much research is being done on making these tools more user friendly? I spent a little bit of time using Coq about a decade ago, and while I agree that it's very important to make things like that widely used, there was a pretty s

Math is a formal science ( https://en.wikipedia.org/wiki/Formal_science ). That term seems to be a little bit obscure, but it's a useful idea.

That matters, but I don't think that's happening until all of the big graduate-level metrics textbooks get R versions. And even then, at least a few papers are going to run into trouble with older reviewers who are used to seeing

When I was in school around 2010 or so, a lot of the younger econ grad students were primarily interested in R. I don't think Stata's going away any time soon, but it might not be completely dominant for that much longer.

Four months is the length of an academic semester, which is the length of a typical introductory programming class. Millions of engineering students around the world succeed at that every year, so there's no reason why you can't.
