If you've read my recent posts then you know that I am highly critical of ESI and Hertzberg.
But it looks like ESI does have some credentials. Here is a bio for Fritz Scheuren who made this presentation for ESI:
Fritz Scheuren
Fritz Scheuren, Ph.D., is a statistical consultant for HRDAG. Recently, Dr. Scheuren consulted on the methods of statistical analysis for Peru's Truth and Reconciliation Commission and reviewed the report of the analysis. In late August of 2003, he visited Peru, along with Dr. Ball and Jana Asher, to meet with representatives of political, military, and civil society groups to explain the technical basis of the findings detailed in the report. In recent years, Dr. Scheuren has advised on the overall direction and approach to the statistical analysis for several HRDAG projects, including Guatemala and Kosovo. As a top statistician in the field, he has also provided critical peer-review of HRDAG work.
Dr. Scheuren is currently the Vice-President for Statistics at the National Opinion Research Center (NORC) and President of the American Statistical Association (ASA). Dr. Scheuren has received numerous awards and honors including: the ASA Founders Award (1998); Shiskin Award for contributions to U.S. Economic Statistics (1995); Finalist, Senior Executive Association Executive Excellence Award, (1992); Elected Member, the International Statistical Institute (1988); Elected Fellow, the American Association for the Advancement of Science (1984); Elected Fellow, the American Statistical Association (1981).
http://www.hrdag.org/about/fritz_scheuren.shtmlI think that Scheuren's credentials make it even more outrageous that they make all these pronouncements without providing the proper backup. In fact, I bet Scheuren is violating a professional guideline of one of the organizations he is an executive of.
