Curve Fitting on JOSS — Library Program Curvefit

D. C. Kephart

ResearchPublished 1974

Curvefit is a set of least squares curve fitting routines for finding the coefficients of empirical equations to fit user specified data. Equations offered include polynomials (straight line, quadratic, cubic, quartic, etc.), and a variety of logarithmic and exponential forms having two or three coefficients. The paper shows how to make most effective use of the routines and includes illustrative printouts of operational runs together with a program listing. The JOSS commands to activate the program are "Recall curvefit from library.", "Do part 1." Instructions are stored with the program.
