Introduction: Andrew Gelman (Columbia University) and Eric Johnson (Columbia University) seek to hire a post-doctoral fellow to work on the application of the latest methods of multilevel data analysis, visualization and regression modeling to an important commercial problem: forecasting retail sales at the individual item level. These forecasts are used to make ordering, pricing and promotions decisions which can have significant economic impact to the retail chain such that even modest improvements in the accuracy of predictions, across a large retailer’s product line, can yield substantial margin improvements. Activities focus on the development of iterative imputation algorithms and diagnostics for missing-data imputation. Activities would include model-development, programming, and data analysis. This project is to be undertaken with, and largely funded by, a firm which provides forecasting technology and services to large retail chains, and which will provide access to a unique and rich

Introduction: Postdoc #1. Hierarchical Modeling and Computation: We are fitting hierarchical regression models with deep interactions. We’re working on new models with structured prior distributions, and this also requires advances in Bayesian computation. Applications include public opinion, climate reconstruction, and education research. Postdoc #1 is funded by grants from the Department of Energy, Institute of Education Sciences, and National Science Foundation. Postdoc #2.

Introduction: See below for the job announcement. It’s for Teachers College, which is about 2 blocks from the statistics department and 2 blocks from the political science department. So even though I don’t have any official connection with Teachers College (besides occasionally working with them on research projects), I very much would like to have another exciting young applied researcher here, to complement all the people we currently have in stat, poli sci, engineering, etc. In particular, we have zillions of interesting and important social science research projects going on here, and they all need statistics work. A lot of social scientists do statistics, but it’s not so easy to find a statistician who does serious social science research. All this is to say that I hope this job gets some applicants from some people who are serious about applied statistics and the development of new models and methods.

Introduction: We’re working with polling company YouGov to track public opinion, state-by-state and district-by-district, during the 2014 campaign. We’ll be using multilevel regression and poststratification, and implementing it in Stan, and developing the necessary new parts of Stan to get this running scalably and efficiently. And we’ll be making the most detailed, up-to-date election forecasts. What you’ll be doing if you join us as a postdoc: - You’ll be in the midst of the most advanced polling team anywhere; - You’ll be doing cutting-edge statistical research on MRP with deep interactions; - You’ll be doing basic research in statistical computing, developing fast and scalable deterministic and stochastic algorithms for fitting multilevel models; - You’ll be working inside Stan, the most advanced general computational framework for Bayesian analysis. We’re doing research, not just implementing existing methods. What we need: - Stats knowledge. You should know your way around Ba

1 0.94264472 314 andrew gelman stats-2010-10-03-Disconnect between drug and medical device approval
Introduction: Sanjay Kaul wrotes: By statute (“the least burdensome” pathway), the approval standard for devices by the US FDA is lower than for drugs. Before a new drug can be marketed, the sponsor must show “substantial evidence of effectiveness” as based on two or more well-controlled clinical studies (which literally means 2 trials, each with a p value of <0.05, or 1 large trial with a robust p value <0.00125). In contrast, the sponsor of a new device, especially those that are designated as high-risk (Class III) device, need only demonstrate "substantial equivalence" to an FDA-approved device via the 510(k) exemption or a "reasonable assurance of safety and effectiveness", evaluated through a pre-market approval and typically based on a single study. What does “reasonable assurance” or “substantial equivalence” imply to you as a Bayesian? These are obviously qualitative constructs, but if one were to quantify them, how would you go about addressing it? The regulatory definitions for

Introduction: Neil Malhotra writes: I just wanted to alert to this completely misinformed Politico article by Roger Simon, equating sampling theory with “magic.” Normally, I wouldn’t send you this, but I sent him a helpful email and he was a complete jerk about it. Wow—this is really bad. It’s so bad I refuse to link to it. I don’t know who this dude is, but it’s pitiful. Andy Rooney could do better. And I don’t mean Andy Rooney in his prime, I mean Andy Rooney right now. The piece appears to be an attempt at jocularity, but it’s about 10 million times worse than whatever the worst thing is that Dave Barry has ever written. My question to Neil Malhotra is . . . what made you click on this in the first place? P.S. John Sides piles on with some Gallup quotes.
