2 0.15749201 1598 andrew gelman stats-2012-11-30-A graphics talk with no visuals!
Introduction: So, I’m at MIT, twenty minutes into my talk on tradeoffs in information graphics to the computer scientists, when the power goes out. They had some dim backup lighting so we weren’t all sitting there in the dark, but the projector wasn’t working. So I took questions for the remaining 40 minutes. It went well, perhaps better than the actual talk would’ve gone, even though they didn’t get to see most of my slides .

Introduction: I received the following (unsolicited) email today: Hello Andrew, I’m interested in whether you are accepting guest article submissions for your site Statistical Modeling, Causal Inference, and Social Science? I’m the owner of the recently created nonprofit site OnlineEngineeringDegree.org and am interested in writing / submitting an article for your consideration to be published on your site. Is that something you’d be willing to consider, and if so, what specs in terms of topics or length requirements would you be looking for? Thanks you for your time, and if you have any questions or are interested, I’d appreciate you letting me know. Sincerely, Samantha Rhodes Huh? P.S. My vote for most obnoxious spam remains this one , which does its best to dilute whatever remains of the reputation of Wolfram Research. Or maybe that particular bit of spam was written by a particularly awesome cellular automaton that Wolfram discovered? I guess in the world of big-time software

Introduction: Corrected equation This post is by Phil. In the comments to an earlier post , I mentioned a problem I am struggling with right now. Several people mentioned having (and solving!) similar problems in the past, so this seems like a great way for me and a bunch of other blog readers to learn something. I will describe the problem, one or more of you will tell me how to solve it, and you will win…wait for it….my thanks, and the approval and admiration of your fellow blog readers, and a big thank-you in any publication that includes results from fitting the model. You can’t ask fairer than that! Here’s the problem. The goal is to estimate six parameters that characterize the leakiness (or air-tightness) of a house with an attached garage. We are specifically interested in the parameters that describe the connection between the house and the garage; this is of interest because of the effect on the air quality in the house if there are toxic chemic

Introduction: In the email the other day, subject line “Casting blogger, writer, journalist to host cable series”: Hi there Andrew, I’m casting a male journalist, writer, blogger, documentary filmmaker or comedian with a certain type personality for a television pilot along with production company, Pipeline39. See below: A certain type of character – no cockiness, no ego, a person who is smart, savvy, dry humor, but someone who isn’t imposing, who can infiltrate these organizations. This person will be hosting his own show and covering alternative lifestyles and secret societies around the world. If you’re interested in hearing more or would like to be considered for this project, please email me a photo and a bio of yourself, along with contact information. I’ll respond to you ASAP. I’m looking forward to hearing from you. *** Casting Producer (646) ***.**** ***@gmail.com I was with them until I got to the “no ego” part. . . . Also, I don’t think I could infiltrate any org

Introduction: Just in time for the new semester: This time I’m sticking with the plan : 1. Don’t open a message until I’m ready to deal with it. 2. Don’t store anything–anything–in the inbox. 3. Put to-do items in the (physical) bookje rather than the (computer) “desktop.” 4. Never read email before 4pm. (This is the one rule I have been following. 5. Only one email session per day. (I’ll have to see how this one works.)

Introduction: How am I supposed to handle this sort of thing? (See below.) I just stuck it one of my email folders without responding, but then I wondered . . . what’s it all about? Is there some sort of Glengarry Glen Ross-like parallel world where down-on-their-luck Jack Lemmons of public relations world send out electronic cold calls? More than anything else, this sort of thing makes me glad I have a steady job. Here’s the (unsolicited) email, which came with the subject line “Please help a reporter do his job”: Dear Andrew, As an Editor for the Bulldog Reporter (www.bulldogreporter.com/dailydog), a media relations trade publication, my job is to help ensure that my readers have accurate info about you and send you the best quality pitches.

3 0.66433185 160 andrew gelman stats-2010-07-23-Unhappy with improvement by a factor of 10^29
Introduction: I have an optimization problem: I have a complicated physical model that predicts energy and thermal behavior of a building, given the values of a slew of parameters, such as insulation effectiveness, window transmissivity, etc. I’m trying to find the parameter set that best fits several weeks of thermal and energy use data from the real building that we modeled. (Of course I would rather explore parameter space and come up with probability distributions for the parameters, and maybe that will come later, but for now I’m just optimizing). To do the optimization, colleagues and I implemented a “particle swarm optimization” algorithm on a massively parallel machine. This involves giving each of about 120 “particles” an initial position in parameter space, then letting them move around, trying to move to better positions according to a specific algorithm. We gave each particle an initial position sampled from our prior distribution for each parameter. So far we’ve run about 140 itera

Introduction: Kaiser Fung tells what it’s really like . Here’s a sample: As soon as I [Kaiser] put the substring-concatenate expression together with two lines of code that generate data tables, it choked. Sorta like Dashiell Hammett without the broads and the heaters. And here’s another take, from a slightly different perspective.
5 0.61889464 996 andrew gelman stats-2011-11-07-Chi-square FAIL when many cells have small expected values
Introduction: William Perkins, Mark Tygert, and Rachel Ward write : If a discrete probability distribution in a model being tested for goodness-of-fit is not close to uniform, then forming the Pearson χ2 statistic can involve division by nearly zero. This often leads to serious trouble in practice — even in the absence of round-off errors . . . The problem is not merely that the chi-squared statistic doesn’t have the advertised chi-squared distribution —a reference distribution can always be computed via simulation, either using the posterior predictive distribution or by conditioning on a point estimate of the cell expectations and then making a degrees-of-freedom sort of adjustment. Rather, the problem is that, when there are lots of cells with near-zero expectation, the chi-squared test is mostly noise. And this is not merely a theoretical problem. It comes up in real examples. Here’s one, taken from the classic 1992 genetics paper of Guo and Thomspson: And here are the e
