Are you ready to go fishing in the data lake?

While Andrew is trying to get someone to make a t-shirt design “Gone fishing”, someone else thinks fishing is one of the “big data trends in 2015″. This advertisement by some company keeps re-appearing in my twitter feed.

On deck this week

Mon: “Unbiasedness”: You keep using that word. I do not think it means what you think it means. [My talk tomorrow in the Princeton economics department] Martin Luther King (2) vs. Sigmund Freud Tues: “A small but growing collection of studies suggest X” . . . huh? Aristotle (3) vs. Stewart Lee Wed: The axes […]

Philip K. Dick (2) vs. Jean Baudrillard

For yesterday, I was gonna go with Vincent, based on X’s comment: In addition to his unique painting style and very special life, van Gogh was highly literate, as shown through the 844 letters from him that are available today. X also made a missing-body-part joke, which I generally don’t think is so cool but, […]

Larry David (4) vs. Thomas Hobbes

Yesterday‘s winner is Chris Rock. “There’s math. And then everything else is debatable.” And now, for today, we have a misanthropists’ version of yesterday’s contest: the grumpy comedian battling it out with the consummate realist political philosopher. Nasty, brutish, and short, indeed. It’s a bit scary how appropriate this matchup is, considering they were all […]

On deck this week

Mon: James Watson sez: Cancer cure is coming in minus 14 years! Chris Rock (3) vs. Jean-Jacques Rousseau Tues: Bayesian survival analysis with horseshoe priors—in Stan! Larry David (4) vs. Thomas Hobbes Wed: VB-Stan: Black-box black-box variational Bayes Jesus (1) vs. Leo Tolstoy Thurs: Another example of why centering predictors can be good idea Mohandas […]

What to graph, not just how to graph it

Robin Gong writes: While we’re on the topic of visualization, I’ve been puzzled by a more general question and I’m unsure where it fits in actually. There seem to be two parts to a good visualization practice, and in our class we’ve been focusing more on one of them, that is “how to get my […]

Statistical distribution of incomes in different countries, and a great plot

This post is by Phil Price. This article in the New York Times is pretty good, and the graphics are excellent…especially the interactive graphic halfway down, entitled “American Incomes Are Losing Their Edge, Except at the Top” (try mousing over the gray lines and see what happens). The plot attempts to display the statistical distribution […]

Shamer shaming

This post is by Phil Price. I can’t recall when I first saw “shaming” used in its currently popular sense. I remember noting “slut shaming” and “fat shaming” but did they first become popular two years ago? Three? At any rate, “shaming” is now everywhere…and evidently it’s a very bad thing. When I first saw […]

If you have a 45% chance of winning, is it “yours to lose”?

Nate Silver gives Brazil a 45% chance of winning the World Cup, with only Argentina and Germany having more than a 10% chance. My gut feeling is that that’s a bit high, but I’m no expert. What I find striking, though, is that the headline says it’s “Brazil’s to lose.” Huh? If we take Silver’s […]

I hate polynomials

A recent discussion with Mark Palko [scroll down to the comments at this link] reminds me that I think that polynomials are way way overrated, and I think a lot of damage has arisen from the old-time approach of introducing polynomial functions as a canonical example of linear regressions (for example). There are very few […]
