Abraham Wald, Allen Wallis, Herbert Solomon,[1] Frederick Mosteller, George Stigler, Leonard Jimmie Savage and Milton Friedman were all part of the group in which 18 researchers participated.
Despite their shared alma mater there is no evidence that Stigler and Friedman had grown close before serving on the SRG staff together in New York City.
"Friedman wrote an appendix called "A Cautionary Tale about Multiple Regressions" that was published in Alternative Approaches to Analyzing Economic Data in which he says that, as a researcher at SRG, he constructed two new alloys to be used in aircraft engines.
His work was based on a regression model that made use of data on existing alloys.
Using this model he predicted that it would take several hundred hours for the new alloys to rupture at high temperatures.
