Non-linear interactive stepwise regression analsis in a time-sharing environment

Time-sharing techniques have created an environment that is capable of supporting a sophisticated generation of mathematical programs. This paper discusses one such program for non-linear stepwise regression analysis in an interactive mode. The principal improvements of this implementation over standard regression programs are the inclusion of the programmer in the control loop (thereby allowing on-line modification of the stepwise regression analysis and non-linear term selection procedures) and the ability of the program to modify itself, i.e., learn, from the results of previous passes of the analysis over the data.
