Edward Wegman is a professor at George Mason and a distinguished statistician with a long career, a former winner of the ASA's Founders Award
. In 2006 he testified before Congress on climate science
, sharply criticizing the statistical methodology of Michael Mann's "hockey stick graph," which showed a sharp increase in global temperature in the last part of the 20th century. One section of Wegman's testimony concerned "social network analysis," and suggested that Mann's tightly-knit network of co-authors might have led to insufficiently aggressive peer review. USA Today reports that Wegman's testimony contained a substantial quantity of plagiarized material, and the peer-reviewed article derived from the testimony has been retracted by the journal that published it.
John Mashey has compiled an obsessively thorough catalogue of the plagiarized text
. (large .pdf.)More USA Today reporting: The journal editor, a friend of Wegman's, accepted the paper 5 days after submission. He insists he got a referee report from an outside reviewer, but that all records of this report were lost when he moved offices. Network analysis expert Kathleen Carley at CMU, asked to read the paper, said, "I see the paper as more of an opinion piece... No data is provided to support this argument."
