This program computes the constants in an equation to give the equation of best fit to a set of data points. The program does both linear and nonlinear curve fitting (i.e. It can find an exponent of best fit!). The user can specify the equation to fit to, allowing much flexibility. The program can use up to 32000 data points in each of 32000 data sets as RAM allows. It can compensate for missing data items, by ignoring those data points. "Best fit" is determined by the usual least squares definition of best fit. The program outputs maximum and average deviations, to allow you to determine which equation works best. For use with MSDOS computers.
