Andrew Gelman - Little Data: How traditional statistical ideas remain relevant in a big-data world

Wanneer:vr 01-11-2013 15:00 - 17:00
Waar:Academiegebouw, Geertsemazaal

On Friday, 1 November at 3pm Andrew Gelman will speak in the Geertsemazaal in the Academiegebouw. His talk, "Little Data: How traditional statistical ideas remain relevant in a big-data world," will touch on the issues involved in learning from data across many fields, including social science, psychology, behavioural genetics, and neuroscience. There will be an opportunity for questions and discussion afterward.

"At the end of the day, after all the processing, big data are being used to answer little-data questions such as, Does an observed pattern generalize to the larger population?, or Could it be explained by alternative processes (sometimes called "chance")?  We discuss some recent ideas in the wolrd of "little data" that remain of big importance."

Andrew Gelman is one of the most widely-known applied statisticians in the world. As director of the Applied Statistics Center at Columbia University, he has done research on a wide range of topics, including: why it is rational to vote; why campaign polls are so variable when elections are so predictable; why redistricting is good for democracy; reversals of death sentences; police stops in New York City, the statistical challenges of estimating small effects; social network structure; toxicology; medical imaging; and methods in surveys, statistical inference, computation, and graphics and and more. He is also the author of a well-read blog, "Statistical Modeling, Causal Inference, and Social Science" ( where he discusses various issues in scientific research generally.
