I started learning Cantonese recently, and the thing that struck me is how insane it is just to get started. Half of my books use Yale romanization, but others use jyutping, so I had to pick up both. Add to that that written Cantonese is Ma

Sorry for the late reply. stringr does a pretty good job (though I like how python handles strings better).

As a person who deeply enjoys developing with python, I'd have to reluctantly say R's tidyverse is a delight to use and often faster than pandas in my experience.

Thanks for the pointers, I'll definitely have to take another look at trinket.io! It would be cool to try some exercise submission + feedback with code highlighting all on the client side.

I work as an engineer at https://datacamp.com , and we run the code directly on a server, but I've always thought it would be interesting to try building interactive programming exercises with Skulpt.

Hmm.. good point. It'd be interesting to think of examples where something with a "complex border" turned out true, and examples where it turned out false. (On a side not, I love this kind of scientific approach to believing

In my experience, most the time people use binning, it's straightforward to demonstrate that their binning+model is equivalent to restricted forms of more general models (e.g. common general additive / structural equation model).

I don't know if they're bad at higher abstractions, or if the pay-off of a higher abstraction isn't always there (or is unclear). The original comment did a good job of illustrating this. It's not clear from this post wh

Wow, this really struck home the idea of useful forms of generality for me. Definitely reminded me of an interesting section in Polya's book Induction and Analogy in Mathematics that discusses different forms of generality, and when i

This article is built around an error in statistical inference. The author uses aggregate data to fit a linear model, then erroneously supposes the slope can be applied to data at the individual level. It can't. For example, there are

Agreed. It seems like side projects for work are basically research (and research is important!).

It seems like early PhD work often involves working at a critical piece that's often overlooked: learning the social landscape of academics (and maybe figuring out what kind of academic they want to be).

For context, I'm pretty sure all of Princeton's grad students are funded (including masters of public administration). Still cool, just wanted to put it out there in case anyone was wondering what their CS dept is up to.

As a memory researcher, I'm a bit puzzled by their criticism that for different learning approaches, few studies qualified for studying long term memory (where long term is defined as 2 years). If there is a difference in retention bet

If one variant beats another, even with very few observations, the data DOES support that one is better. It's just that you might not be very confident that one is better. The key to understanding this situation statistically is by ref

If you are waiting for N observations, so that a NHST will have some level of power, and you assume each observations is drawn from the same distribution (as your test likely does), then you do not see each observation as noise. You will ju

I disagree, if a person has to make a decision under uncertainty, and a priori favors neither group A or B, then they might as well use any visitor information available to them to guide their choice. They just shouldn't be too confide

At first I was confused, because statistical models that aren't temporally independent are very common. But it's very clear from the comments that having dice that aren't independent between rolls is incredibly in demand :o,

Slightly off-topic, but the pushback against brain training owes a huge debt of thanks to Randy Engle (and others), for loudly questioning the methods and rational of the early "become smarter by the magic of dual n-back" research
