They don’t fit into their categories

March 14, 2015
By

I was reading the newspaper today and came across an article entitled, “Black Holes Inch Ahead to Violent Cosmic Union.” No big deal, except that it was in the National section. Not the International. This reminded me of other examples where items didn’t fit into their categories, for example when Slate magazine published an article, […] The post They don’t fit into their categories appeared first on Statistical Modeling, Causal…

Simone de Beauvoir (2) vs. Chris Rock (3); Wood advances

You guys keep making it tough for me! Yesterday I was strongly rooting for Turing—really, I have no interest in seeing Ed Wood speak at all, and if he ever makes into the finals against John Waters he’ll just get destroyed—but Anonymous wins the thread with the very first comment: I vote against Turing — […] The post Simone de Beauvoir (2) vs. Chris Rock (3); Wood advances appeared first…

De-weaponizing reproducibility

March 13, 2015
By

A couple of weeks ago Roger and I went to a conference on statistical reproducibility held at the National Academy of Sciences. The discussion was pretty wide ranging and I love that the thinking about reproducibility is coming back to statistics. There was pretty widespread support for the idea that prevention is the right way to approach

Toon Kuppens writes: After a discussion on a multilevel modeling mailing list, I came across this one-year-old blog post written by you. You might be interested to know that in social psychology, taking the aggregate outcome variable to predict the outcome variable has been used as a test of ‘convergence’, the phenomenon that people’s responses […] The post Using y.bar to predict y: What’s that all about?? appeared first on…

I was going to call yesterday‘s match for Leonardo, based on Tom’s comment: I’ve been wondering how often a weak player / team gets to a final because they mostly come across weaker opposition and get a bit of luck. I think that Leonardo is the type of guy who could invent a remarkable device […] The post Ed Wood (3) vs. Alan Turing (2); Levi-Strauss advances appeared first on…

Stock-and-flow and other concepts that are important in statistical modeling but typically don’t get taught to statisticians

March 12, 2015
By

Bill Harris writes: You’ve written about causality somewhat often, and you, along with perhaps everyone who has done anything with statistics, have written that “correlation is not causation.” When you say that correlation is not causation, you seem to be pointing out cases where correlation exists but causality does not. While that’s important, there’s another […] The post Stock-and-flow and other concepts that are important in statistical modeling but typically…

Common reasons for rejection

Every week I reject some papers submitted to the International Journal of Forecasting, without sending the papers off to associate editors or reviewers. Here are five of the most common reasons for rejection. 1. Wrong Journal Submissions to the IJF should be about forecasting, obviously. But we often get papers on econometrics, or time series […]

Matrix multiplication with missing values in SAS

Sometimes I get contacted by SAS/IML programmers who discover that the SAS/IML language does not provide built-in support for multiplication of matrices that have missing values. (SAS/IML does support elementwise operations with missing values.) I usually respond by asking what they are trying to accomplish, because mathematically matrix multiplication with […] The post Matrix multiplication with missing values in SAS appeared first on The DO Loop.

One of America’s leading political columnists, David Brooks, has just come out with a column called “The Cost of Relativism” about the growing chasm between college-educated America and those who write for major newspapers.
