Think Bayes: Bayesian Statistics Made Simple

By some piece of luck, I came upon the book Think Bayes: Bayesian Statistics Made Simple, written by Allen B. Downey and published by Green Tea Press [which I could relate to No Starch Press, focussing on coffee!, which published Statistics Done Wrong that I reviewed a while ago] which usually publishes programming books with […]

More chart drama, and data aggregation

Robert Kosara posted a response to my previous post. He raises an important issue in data visualization - the need to aggregate data, and not plot raw data. I have no objection to that point. What was shown in my...

Don’t miss this one:  “Modern Physics from an Elementary Point of View”

I was googling *back of the envelope* for a recent post and I came across these lecture notes by Victor Weisskopf from 1969. I can no longer really follow this sort of thing—I really really wish this had been my textbook back when I was studying physics. If they’d taught us this stuff, I might’ve […] The post Don’t miss this one: “Modern Physics from an Elementary Point of View”…

Theranos and ethics

I have to admit I missed the hype about Elizabeth Holmes, and only learned about her from the Wall Street Journal hit job that came out last week (link). It feels like I arrived to the party after the police has shut the fun down! Holmes had been profiled in all the important places--no doubt many of her interviewers are feeling a bit red-faced. She dropped out of Stanford to…

Exact tests in PROC FREQ: What, when, and how

Did you know that the FREQ procedure in SAS can compute exact p-values for more than 20 statistical tests and statistics that are associated with contingency table? Mamma mia! That's a veritable smorgasbord of options! Some of the tests are specifically for one-way tables or 2 x 2 tables, but many apply […] The post Exact tests in PROC FREQ: What, when, and how appeared first on The DO Loop.

When Details Hide the Story

Kaiser Fung doesn’t like this graphic that accompanied a recent story about the bird flu in the Wall Street Journal. His redesign shows a lot less overlap and a lot more detail; so much, in fact, that it obscures the point of the chart. Here is the offending graphic. The overlapping circles are hard to read with … Continue reading When Details Hide the Story

Predictive Accuracy Rankings by MSE vs. MAE

October 25, 2015
By

We've all ranked forecast accuracy by mean squared error (MSE) and mean absolute error (MAE), the two great workhorses of relative accuracy comparison. MSE-rankings and MAE-rankings often agree, but they certainly don't have to -- they're simply differ...

Top 5 movies about scientists

In this NYT interview, Philip “Stanford Prison Experiment” Zimbardo gives his list: 1. “Madame Curie,” 1943 2. “The Seven-Per-Cent Solution,” 1976 3. “Awakenings,” 1990 4. “The Insider,” 1999 5. “The Imitation Game,” 2014. Not a very impressive list. But that’s the point, I guess: there haven’t been many good movies about scientists. I was racking […] The post Top 5 movies about scientists appeared first on Statistical Modeling, Causal Inference,…
