Recognising Uncertainty in Statistics

100x100-the-engine-roomIn Responsible Data Reflection Story #7—from the Responsible Data Forum—work by HRDAG affiliates Anita Gohdes and Brian Root is cited extensively to make the point about how quantitative data are the result of numerous subjective human decisions. An excerpt: “The Human Rights Data Analysis Group are pioneering the way in collecting and analysing figures of killings in conflict in a responsible way, using multiple systems estimation.”


Improving the estimate of U.S. police killings

Cory Doctorow of Boing Boing writes about HRDAG executive director Patrick Ball and his contribution to Carl Bialik’s article about the recently released Bureau of Justice Statistics report on the number of annual police killings, both reported and unreported, in 538 Politics.


Multiple Systems Estimation: The Basics

Multiple systems estimation, or MSE, is a family of techniques for statistical inference. MSE uses the overlaps between several incomplete lists of human rights violations to determine the total number of violations. In this blogpost, and four more to follow, I’ll answer both conceptual and practical questions about this important method. (In posts to follow, questions that refer to specific statistical procedures or debates will be marked, "In depth.") (more…)

HRDAG and the Trial of José Efraín Ríos Montt

At some point in the next week, HRDAG's executive director, Patrick Ball, will be providing expert testimony in the trial of General José Efraín Ríos Montt, the de-facto president of Guatemala in 1982-1983. Gen. Ríos is being tried on charges of genocide and crimes against humanity. (His military intelligence director, Gen. Mauricio Rodríguez Sánchez is also on trial.) Patrick will testify on approximately April 15-18, 2013, and he may begin as early as this Friday, April 12. The trial opened on March 20, 2013, in the Supreme Court building in Guatemala City. According to an Open Society Justice Initiative blogpost covering the event, the ...

Gaza death toll 40% higher than official number, Lancet study finds

“Patrick Ball, a statistician at the US-based Human Rights Data Analysis Group not involved in the research, has used capture-recapture methods to estimate death tolls for conflicts in Guatemala, Kosovo, Peru and Colombia.

Ball told AFP the well-tested technique had been used for centuries and that the researchers had reached “a good estimate” for Gaza.”


Karl E. Peace Award Recognizes Work of Patrick Ball

Sierra Leone TRC Data and Statistical Appendix

HRDAG assisted the Sierra Leone Truth and Reconciliation Commission in building a systematic data coding system, electronic database, and secure data analysis process to manage the thousands of statements given to them in the course of their work. HRDAG executive director Patrick Ball and HRDAG field consultant Richard Conibere worked at the TRC full-time for approximately eighteen months starting in March 2003. HRDAG worked with TRC researchers to help them incorporate quantitative findings to support the qualitative findings in their writing for the other chapters of the TRC report. In addition, HRDAG produced a Statistical Appendix to present ...

Welcome!

As of today, the Human Rights Data Analysis Group (HRDAG) is an independent* non-profit! It's been a long time coming, and we're delighted to have gotten to this point. HRDAG is a non-profit, non-partisan organization that applies rigorous science to the analysis of human rights violations around the world; for more information, see our About Us page. Benetech has spun out the scientific and statistical part of the Human Rights Program to HRDAG. The spinout includes (as staff) me -- Patrick Ball -- and Dr Megan Price, as well as our many part-time scientific and field consultants (a list is here). The software and technology component of our work -- ...

Reflections: Some Stories Shape You

The first time I met anyone at HRDAG, I was a journalist. It was 2006. I was working on a story about a graduate student at Carnegie Mellon who’d collaborated with the organization on a survey in Sierra Leone, and I contacted Patrick Ball to discuss the work. At the time, I found him challenging. But I thought his work—trying to estimate how many people were killed, or, in that study, otherwise injured, during wars—was fascinating. Over the next few years, I got to know other researchers working on similar questions. In 2008, as the war in Iraq ramped up, I spoke with epidemiologists from Johns Hopkins University, the World Health Organiz...

Perú

In 2001, President Alejandro Toledo, called for the establishment of the Comision de la Verdad y Reconciliacion (CVR) (Truth and Reconciliation Commission) to investigate human rights abuses in Perú between 1980 and 2000. Dr. Patrick Ball was invited to work with the Commission to evaluate the CVR technical work and make recommendations on the information management process and analytic strategies. HRDAG consultant Jana Asher worked with Dr. Ball and CVR staff members David Sulmont (Director Informations Systems) and Daniel Manrique (Database Expert) to present evidence of the violations in a report to the CVR. The work included new estimates of ...

Quantifying Injustice

“In 2016, two researchers, the statistician Kristian Lum and the political scientist William Isaac, set out to measure the bias in predictive policing algorithms. They chose as their example a program called PredPol.  … Lum and Isaac faced a conundrum: if official data on crimes is biased, how can you test a crime prediction model? To solve this technique, they turned to a technique used in statistics and machine learning called the synthetic population.”
