Abstract : Stepwise regression analysis is a least squares method for estimating an empirical linear relationship between variables. This method is implemented by the computer program STRAP with FORMAT, Version 2, for the IBM 1620 Card or Paper Tape Data Processing System with 20,000 positions of storage and no special features. Some of the capabilities of this program are found only in programs for very large machines, if at all. The many statistics, optional output and flexible data formats provide a powerful program to satisfy the requirements for many applications at the Laboratory. (Author)
