TECHNIQUES FOR THE SUMMATION OF PRODUCTS ON HOLLERITH AND NATIONAL ACCOUNTING MACHINES
( Mathematical Institute, University of Liverpool )
Methods of evaluating sums of products applicable to numerical quadrature, Fourier analysis and synthesis, the evaluation of serial correlations, and other computations with Hollerith punched card equipment, are described briefly. One method is substantially new. Also given are the modifications required for making the methods applicable for use with National accounting machines, the use of which, in this type of work, is entirely new. Emphasis is placed throughout on the most economical use of machines and on the incorporation of checks.
