2 0.16624919 438 andrew gelman stats-2010-11-30-I just skyped in from Kentucky, and boy are my arms tired
Introduction: I just gave my first Skype presentation today, and it felt pretty strange. The technical difficulties mostly arose with the sound. There were heavy echoes and so we ended up just cutting off the sound from the audience. This made it more difficult for me because I couldn’t gauge audience reaction. It was a real challenge to give a talk without being able to hear the laughter of the audience. (I asked them to wave their hands every time they laughed, but they didn’t do so–or else they were never laughing, which would be even worse.) Next time I’ll use the telephone for at least one of the sound channels. The visuals were ok from my side–I just went thru my slides one by one, using the cursor to point to things. I prefer standing next to the screen and pointing with my hands. But doing it this way was ok, considering. The real visual problem went the other way: I couldn’t really see the audience. From the perspective of the little computer camera, everyone seemed far away

Introduction: I’ve always thought it looked strange to see people referred to in print as Black or White rather than black or white. For example consider this sentence: “A black guy was walking down the street and he saw a bunch of white guys standing around.” That looks fine, whereas “A Black guy was walking down the street and he saw a bunch of White guys standing around”—that looks weird to me, as if the encounter was taking place in an Ethnic Studies seminar. But maybe I’m wrong on this. Jay Livingston argues that black and white are colors whereas Black and White are races (or, as I would prefer to say, ethnic categories) and illustrates with this picture of a white person and a White person: In conversation, I sometimes talk about pink people, brown people, and tan people, but that won’t work in a research paper. P.S. I suspect Carp will argue that I’m being naive: meanings of words change across contexts and over time. To which I reply: Sure, but I still have to choose h

Introduction: A few weeks ago I delivered a 10-minute talk on statistical graphics that went so well, it was the best-received talk I’ve ever given. The crowd was raucous. Then some poor sap had to go on after me. He started by saying that my talk was a hard act to follow. And, indeed, the audience politely listened but did not really get involved in his presentation. Boy did I feel smug. More recently I gave a talk on Stan, at an entirely different venue. And this time the story was the exact opposite. Jim Demmel spoke first and gave a wonderful talk on optimization for linear algebra (it was an applied math conference). Then I followed, and I never really grabbed the crowd. My talk was not a disaster but it didn’t really work. This was particularly frustrating because I’m really excited about Stan and this was a group of researchers I wouldn’t usually have a chance to reach. It was the plenary session at the conference. Anyway, now I know how that guy felt from last month. My talk

Introduction: I spoke at the University of Kansas the other day. Kansas is far away so I gave the talk by video. We did it using a G+ hangout, and it worked really well, much much better than when I gave a talk via Skype . With G+, I could see and hear the audience clearly, and they could hear me just fine while seeing my slides (or my face, I went back and forth). Not as good as a live presentation but pretty good, considering. P.S. And here’s how to do it! Conflict of interest disclaimer: I was paid by Google last year to give a short course.

3 0.80796963 407 andrew gelman stats-2010-11-11-Data Visualization vs. Statistical Graphics
Introduction: I have this great talk on the above topic but nowhere to give it. Here’s the story. Several months ago, I was invited to speak at IEEE VisWeek. It sounded like a great opportunity. The organizer told me that there were typically about 700 people in the audience, and these are people in the visualization community whom I’d like to reach but normally wouldn’t have the opportunity to encounter. It sounded great, but I didn’t want to fly most of the way across the country by myself, so I offered to give the talk by videolink. I was surprised to get a No response: I’d think that a visualization conference, of all things, would welcome a video talk. In the meantime, though, I’d thought a lot about what I’d talk about and had started preparing something. Once I found out I wouldn’t be giving the talk, I channeled the efforts into an article which, with the collaboration of Antony Unwin, was completed about a month ago. It would take very little effort to adapt this graph-laden a
Introduction: See if you can interpolate the talk from the slides . The background is: I was invited to speak in this seminar on “big data.” I said I didn’t know anything about big data, I worked on little data. They said that was ok. Actually it was probably a crowd-pleasing move to tell these people that little-data ideas remain relevant.

2 0.8714335 1874 andrew gelman stats-2013-05-28-Nostalgia
Introduction: Saw Argo the other day, was impressed by the way it was filmed in such a 70s style, sorta like that movie The Limey or an episode of the Rockford Files. I also felt nostalgia for that relatively nonviolent era. All those hostages and nobody was killed. It’s a good thing the Ayatollah didn’t have some fundamentalist Shiite equivalent of John Yoo telling him to waterboard everybody. At the time we were all so angry and upset about the hostage-taking, but from the perspective of our suicide-bomber era, that whole hostage episode seems so comfortingly mild.
3 0.78961706 393 andrew gelman stats-2010-11-04-Estimating the effect of A on B, and also the effect of B on A
Introduction: Lei Liu writes: I am working with clinicians in infectious disease and international health to study the (possible causal) relation between malnutrition and virus infection episodes (e.g., diarrhea) in babies in developing countries. Basically the clinicians are interested in two questions: does malnutrition cause more diarrhea episodes? does diarrhea lead to malnutrition? The malnutrition status is indicated by height and weight (adjusted, HAZ and WAZ measures) observed every 3 months from birth to 1 year. They also recorded the time of each diarrhea episode during the 1 year follow-up period. They have very solid datasets for analysis. As you can see, this is almost like a chicken and egg problem. I am a layman to causal inference. The method I use is just to do some simple regression. For example, to study the causal relation from malnutrition to diarrhea episodes, I use binary variable (diarrhea yes/no during months 0-3) as response, and use the HAZ at month 0 as covariate
4 0.75658518 1498 andrew gelman stats-2012-09-16-Choices in graphing parallel time series
Introduction: I saw this graph posted by Tyler Cowen: and my first thought was that the bar plot should be replaced by a line plot: Six lines, one for each income category, with each line being a time series of these changes. With a line plot, you can more easily see each time series (these are hard to see in the barplot because you have to follow each color and jump from decade to decade) and also compare the patterns for each category. The line plot pretty much dominates the bar plot. At least that was the theory. Now here’s what actually happened. I downloaded the data as Excel files, saved them as csv, then read them into R. In all, it took close to an hour to get the data set up in the format that was needed to make the graphs. At this point it was pretty easy to make the line plot. But the result was disappointing: The six lines are hard to untangle (sure, a better color scheme might help, but it wouldn’t really solve the problem) and the graph as a whole is much l

Introduction: Anupam Agrawal writes: I am an Assistant Professor of Operations Management at the University of Illinois. . . . My main work is in supply chain area, and empirical in nature. . . . I am working with a firm that has two separate divisions – one making cars, and the other makes trucks. Four years back, the firm made an interesting organizational change. They created a separate group of ~25 engineers, in their car division (from within their quality and production engineers). This group was focused on improving supplier quality and reported to car plant head . The truck division did not (and still does not) have such an independent “supplier improvement group”. Other than this unit in car, the organizational arrangements in the two divisions mimic each other. There are many common suppliers to the car and truck division. Data on quality of components coming from suppliers has been collected (for the last four years). The organizational change happened in January 2007. My focus is
