رگرسیون خطی و همبستگی: راهنمای مبتدیان

From the Foreword. In 1949, while I was visiting Ezra Pound who was a political prisoner at St. Elizabeth's Hospital, Washington, D.C. (a Federal institution for the insane), Dr. Pound asked me if I had ever heard of the Federal Reserve System. I replied that I had not, as of the age of 25. He then showed me a ten dollar bill marked "Federal Reserve Note" and asked me if I would do some research at the Library of Congress on the Federal Reserve System which had issued this bill. Pound was unable to go to the Library himself, as he was being held without trial as a political prisoner by the United States government. After he was denied broadcasting time in the U.S., Dr. Pound broadcast from Italy in an effort to persuade people of the United States not to enter World War II. Franklin D. Roosevelt had personally ordered Pound's indictment, spurred by the demands of his three personal assistants, Harry Dexter White, Lauchlin Currie, and Alger Hiss, all connected with Communist espionage.
