Elites have alcohol problems too!

Speaking of Tyler Cowen, I’m puzzled by this paragraph of his: Guns, like alcohol, have many legitimate uses, and they are enjoyed by many people in a responsible manner. In both cases, there is an elite which has absolutely no problems handling the institution in question, but still there is the question of whether the [...]

Data science is statistics

When physicists do mathematics, they don’t say they’re doing “number science”. They’re doing math. If you’re analyzing data, you’re doing statistics. You can call it data science or informatics or analytics or whatever, but it’s still statistics. If you say that one kind of data analysis is statistics and another kind is not, you’re not […]

The Revolution Will Be Visualized

In the 1970s, it was the protest songs. In the 1980s, it was the anti-war movies. Today, the protest is no longer happening in songs or movies. Today, it’s online, based on data, and using visualization. Gun Deaths It’s a very abstract and yet very clear image: something moves along a trajectory, is suddenly stopped, and drops to the ground.

Alexander Volfovsky and Peter Hoff write: ANOVA decompositions are a standard method for describing and estimating heterogeneity among the means of a response variable across levels of multiple categorical factors. In such a decomposition, the complete set of main effects and interaction terms can be viewed as a collection of vectors, matrices and arrays that [...]

Beware of grep with a list

Another R tip: beware of as.character applied to a list. Really, beware of grep with a list: You might have thought that the result would be just 1, but grep expects a vector of character strings. If the input is not that, it uses as.character(). Since the result of that starts with "c(", grep finds […]

apply vs for

It’s widely understood that, in R programming, one should avoid for loops and always try to use apply-type functions. But this isn’t entirely true. It may have been true for Splus, back in the day: As I recall, that had to do with the entire environment from each iteration being retained in memory. Here’s a […]
