Boissevain, his friend and head of the Colorado Foundation for Research in Tuberculosis, advised him that multiple-correlation analysis could be applied to economic research, and recommended that he speak to Harold T. Davis, a mathematician at Indiana University who spent his summers in Colorado Springs and a member of the fledgling Econometric Society.
[9] When it turned out that the machines were ill-suited to the task, Cowles decided to perform a series of linear regressions to test the hypothesis that market analysts using current estimation techniques could not outperform random guessing.
[6] Encouraged by Davis, Cowles wrote to Yale economist Irving Fisher to offer funding for the Econometric Society and to underwrite a new academic journal, Econometrica, in return for Fisher's assistance in assembling a "brain trust" of leading scholars to work with the Cowles Commission.
[9][8][3]: 193 In addition to Harold T. Davis, methodological guidance in the early years was provided by actuarial mathematician James Glover of University of Michigan and Thornton Fry of Bell Laboratories.
