2:00 PM | Paul Meehl continues to be the boss
Lee Sechrest writes: Here is a remarkable paper, not well known, by Paul Meehl. My research group is about to undertake a fresh discussion of it, which we do about every five or ten years. The paper is now more than a quarter of a century old but it is, I think, dramatically pertinent to […] The post Paul Meehl continues to be the boss appeared first on Statistical Modeling, Causal Inference, and Social Science.

11:15 PM | ABC for copula estimation
Clara Grazian and Brunero Liseo (di Roma) have just arXived a note on a method merging copulas, ABC, and empirical likelihood. The approach is rather hybrid and thus not completely Bayesian, but this must be seen as a consequence of an ill-posed problem. Indeed, as in many econometric models, the model there is not fully […]

7:00 PM | PRIMES Dominates High School Research
The 2015 Intel Science Talent Search results are out. This year they divided the prizes into three categories: basic research, global good, and innovation. All three top prizes in basic research were awarded to our PRIMES students: First place: Noah Golowich, Resolving a Conjecture on Degree of Regularity, with some Novel Structural Results Second place: […]

6:58 PM | Puzzling Grades
I lead recitations for a Linear Algebra class at MIT. Sometimes my students are disappointed with their grades. The grades are based on the final score, which is calculated by the following formula: 15% for homework, 15% for each of the three midterms, and 40% for the final. After all the scores are calculated, we […]

4:27 PM | Zio Paperone e la grande avventura dell'acqua
Oggi, in occasione della giornata internazionale dell'acqua (leggi anche OggiScienza), recupero un estratto (modificato) di un post dedicato alla storia Zio Paperone e la grande avventura acquatica di Valentina Camerini e Marco MazzarelloI protagonisti della storia sono Archimede Pitagorico accompagnato da Paperone e da Paperinik. I tre paperi, mentre stanno rimpicciolendo alcuni iceberg, vengono per sbaglio ridotti a dimensioni atomiche dall'ultima invenzione di Archimede, riducendosi fino […]

4:21 PM | I marmocchi di Agnes
Durante le mie vacanze estive ho girato poco per librerie. Anzi, purtroppo sono andata in libreria solo due volte, delle quali una molto veloce. Però, nel mio primo giro, oltre un libro per bambini, ho acquistato due libri anche per me, uno dei quali è il seguito di "Agnes Browne mamma". La curiosità di sapere come sono continuate le vite della famiglia Browne era troppo grande!Agnes Browne ha continuato la sua vita di mamma/papà e venditrice di frutta e verdura al […]

4:00 PM | Judy Garland (4) vs. John Waters (1); Carlin advances
Not a lot of action on yesterday‘s post, so I don’t think the winner will advance any farther . . . But, in any case, I’ll call it for Carlin based on Jonathan’s amusing babble of postmodernist commentary. As for today: What can you say? A great pairing to close out the second round of […] The post Judy Garland (4) vs. John Waters (1); Carlin advances appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:20 PM | Why I don’t use the terms “fixed” and “random” (again)
A couple months ago we discussed this question from Sean de Hoon: In many cross-national comparative studies, mixed effects models are being used in which a number of slopes are fixed and the slopes of one or two variables of interested are allowed to vary across countries. The aim is often then to explain the […] The post Why I don’t use the terms “fixed” and “random” (again) appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:18 PM | a marathon a day for… a year?!
“I think a lot of people do not push themselves enough.” Rob Young I found this Guardian article about Rob Young and his goal of running the equivalent of 400 marathons in 365 days. Meaning there are days he runs the equivalent of three marathons. Hard to believe, isn’t it?! But his terrible childhood is […]

5:18 AM | Clique minors in de Bruijn graphs
In my new Wikipedia article on the queue number of graphs, the binary de Bruijn graphs form an important family of examples. These are 4-regular graphs with one vertex for every n-bit binary string, and with an edge from every string of the form 0s or 1s to s0 or s1. I posted about them here several years ago, with the following drawing, which can be interpreted as a 2-queue drawing with one queue for the edges that wrap around the left side and another for the edges that wrap around the […]

1:06 AM | What a Mathematician should visit in Florence
Long time since I last posted something like this, but I do remember you enjoyed it a lot, so I thought that I should finally do this one. Yesterday was the 1st day of spring and soon it’s summer and most of us (including myself ^_^) still have to plan their summer holidays. As you […]

11:15 PM | Dom Juan’s opening
The opening lines of the Dom Juan plan by Molière, a play with highly subversive undertones about free will and religion. And this ode to tobacco that may get it banned in Australia, if the recent deprogramming of Bizet’s Carmen is setting a trend! [Personal note to Andrew: neither Molière’s not my research are or […]

8:58 PM | a mad afternoon!
An insanely exciting final day and end to the 2015 Six Nations tournament! on the first game of the afternoon, Wales beat Italy in Rome by a sound 20-61!, turning them into likely champions. But then, right after, Ireland won against Scotland 10-40! In mythical Murrayfield. A feat that made them winners unless England won […]

6:19 PM | Raccontare l'eclissi
foto di Luca Di FinoQuando il saggio indica la luna, lo stolto guarda l'eclissi. E si brucia la retina. E il saggio si ammazza dalle risate.Enrico MiceliDopo le foto di ieri, una raccolta di tweet e link e citazioni. Iniziamo con una serie di tweet di Giorgio Sestili segnalati da Luca Di Fino:Pensate alle popolazioni passate, che nulla sapevano sull'eclissi e sul moto dei pianeti. Improvvisamente, in pieno giorno, il buio! [1]Presagi funesti, segni anticipatori di sventure, sovvertimento […]

4:00 PM | George Carlin (2) vs. Jacques Derrida; Updike advances
Yesterday‘s best comment comes from Zbicyclist, who wrote: My wife would prefer I not go to a talk by someone who wrote so extensively about adultery. But of course that would rule out both John Updike and Bertrand Russell. We could use “number of wives” as a tiebreaker, but instead I’ll go with Updike based […] The post George Carlin (2) vs. Jacques Derrida; Updike advances appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:02 PM | “How the Internet Scooped Science (and What Science Still Has to Offer)”
Brian Silver pointed me to this post from Andrew Lindner: This week, my manuscript, co-authored by Melissa Lindquist and Julie Arnold, “Million Dollar Maybe? The Effect of Female Presence in Movies on Box Office Returns” was published online by Sociological Inquiry. It will appear in print later this year. So far, no surprises. A researcher […] The post “How the Internet Scooped Science (and What Science Still Has to Offer)” appeared first on Statistical Modeling, […]
