Center for Statistics and Applications in Forensic Evidence

This week I have been visiting the new Center for Statistics and Applications in Forensic Evidence. The center involves four universities, CMU, ISU, UC-Irvine, U. Virginia, and is a NIST Center of Excellence. The kickoff event occurred over Oct 26-27 at ISU, organized by Center Director, Professor Alicia Carriquiry. The speaker list included Barry Scheck (Co-Founder, The Innocence Project), Jo Handelsman (The White House Office of Science & Technology Policy), Philip Dawid (Emeritus Professor of Statistics, University of Cambridge), Anil Jain (Michigan State University) and Stephen Feinberg (CMU).

Graduates in Statistical Graphics Research at ISU 2015

Its exciting to report on the graduations from the working group this year. Niladri Roy Chowdhury defended his PhD thesis in Aug 2014, titled “Explorations of the lineup protocol for visual inference: application to high dimension, low sample size problems and metrics to assess the quality”, under my direction. He is a scientist at Novartis, Boston, MA. Susan Vanderplas defended her PhD in May, titled “Perception in Statistical Graphics”, under the direction of Professor Heike Hofmann.

EDA at the UN

On Nov 10 I was part of a celebration of John W. Tukey at the United Nations. This event kicked off a new UN initiative called Unite Ideas. Details of the event, and the initiative can be found here. There were five talks relayed live to an audience of several thousand, using google hangouts and a youtube channel, and listeners could post questions using the Q/A tool. My talk was titled “An Exploratory Data Analysis of OECD’s 2012 PISA Survey”s and I delivered it by computer from my office in Iowa.

New version of nullabor package released

The new version of nullabor contains numerical measures that quantify how close the plot of the data is to the null plots in a lineup. It is very difficult to quantify all patterns that might be read from plots, so these should be taken in a spirit ofa Herculean task. The goal is to get some sense of what people are reacting to in a plot, which could be then associated with the text descriptions from people, or with data from an eyetracker.

Statistical computing research

During the week, I received final confirmation notice that the special issue of Statistical Science that Vince Carey and I put together is finally published. There are four papers from leaders in the field of statistical computing research: John Chambers, Duncan Temple Lang, Michael Lawrence and Michael Morgan (newly minted members of R Core) and Yihui Xie, Heike Hofmann and Xiaoyue Cheng. The links to the overview and the four papers are below.

How good is Nick Kygrios?

Nick Kygrios caught the world’s attention in July at Wimbledon 2014 when he beat world number 1 Rafael Nadal. After the match McEnroe commented: “We’ve been waiting for this for a while. We keep saying, `Who’s the next guy?‘, and I think we found that guy right now.” http://dailym.ai/1jlEfrc. but Nadal seemed to beg to differ: “He has things, positive things, to be a good player. But everything is a little bit easier when you are arriving.
