A simple program in BASIC for least-squares fitting of certain equations to experimental data

A program is presented that fits certain classes of theoretical equations to experimental data by the method of least squares. Equations that can be fitted by this program include all one-parameter functions and those two-parameter functions in which one of the parameters is a multiplicative factor. The program is in BASIC and thus can be used on any microcomputer equipped with that language, and its use is guided by on-screen prompts.
