Cumulative residual plots seem like they could be useful

August 23, 2017
By

Peter Vanney, a statistician at Texas Highway Patrol, writes: I’m wondering if you could comment on CURE (CUmulative REsidual) plots that I’m seeing quite a bit in vehicle crash modeling. Ezra Hauer and Joseph Bamfo champion them as a way to determine model fit for their hierarchical Bayesian generalized linear mixed models. I had not […] The post Cumulative residual plots seem like they could be useful appeared first on…

Don’t always give ’em what they want: Practicing scientists want certainty, but I don’t want to offer it to them!

Stephen Senn writes: What the practicing scientist wants to know is what is a good test in practice. I agree with Stephen Senn on most things—even where it seems we disagree, I think we agree on the fundamentals—but in this case I think you have to be careful about giving the practicing scientist what he […] The post Don’t always give ’em what they want: Practicing scientists want certainty, but…

Ron Kennett sent along these two papers: Statistics: A Life Cycle View Aspects of statistical consulting not taught by academia Also this presentation. They’re somewhat relevant to our current project on statistical workflow, so I’m posting them here for convenience. P.S. I used to think it was a good idea to teach statistical consulting, and […] The post Two papers and one presentation by Ron Kennett related to workflow appeared…

Harvey Rosen writes: My query is similar to the one from André Ariew that you posted on August 7, in which he asked if you could suggest readings for his graduate course in philosophy. I occasionally teach an undergraduate course on introductory microeconomics. I like to devote some time to discussing challenges to economists’ conventional […] The post He wants some readings on the replication crisis that are accessible to…

Publish your raw data and your speculations, then let other people do the analysis: track and field edition

August 21, 2017
By

There seems to be an expectation in science that the people who gather a dataset should also be the ones who analyze it. But often that doesn’t make sense: what it takes to gather relevant data has little to do with what it takes to perform a reasonable analysis. Indeed, the imperatives of analysis can […] The post Publish your raw data and your speculations, then let other people do…

Irish immigrants in the Civil War

August 20, 2017
By

I was cc-ed on a series of emails on a topic I know nothing about, maybe because I’m on the political science faculty here, I don’t know. Anyway, there was some statistical content here so I thought I’d share with you. The email is from James McManus: Analysis of the Civil War Immigrant problem McPherson’s […] The post Irish immigrants in the Civil War appeared first on Statistical Modeling, Causal…

“Babbage was out to show that not only was the system closed, with a small group controlling access to the purse strings and the same individuals being selected over and again for the few scientific honours or paid positions that existed, but also that one of the chief beneficiaries . . . was undeserving.”

Fernando Martel Garcia writes: Here’s an early reference from the Victorian Age. Enjoy! It’s a news article by Rebekah Higgitt called “Fraud and the decline of science,” subtitled, “Charles Babbage’s accusations of fraudulent science underlined his attack on scientific governance, but were also bitterly personal.” My reply: Wow! I think I’m on Babbage’s side on […] The post “Babbage was out to show that not only was the system closed,…

It is somewhat paradoxical that good stories tend to be anomalous, given that when it comes to statistical data, we generally want what is typical, not what is surprising. Our resolution of this paradox is . . .

August 18, 2017

From a blog comment a few years ago regarding an article by Robert Kosara: As Thomas and I discuss in our paper [When Do Stories Work? Evidence and Illustration in the Social Sciences], it is somewhat paradoxical that good stories tend to be anomalous, given that when it comes to statistical data, we generally want […] The post It is somewhat paradoxical that good stories tend to be anomalous, given…

Just google “Despite limited statistical power”

August 17, 2017
By

Here it is. It’s not always clear what people mean by this expression, but sometimes it seems that they’re making the “What does not kill my statistical significance makes it stronger” fallacy, thinking that the attainment of statistical significance is a particular feat in the context of a noisy study, so that they’re (mistakenly) thinking […] The post Just google “Despite limited statistical power” appeared first on Statistical Modeling, Causal…
