DESCRIPTION OF PROGRAM
LSTSQR is a program designed to carry out a least-squares fit of data to
one or more of several functional forms, including linear, polynomial,
logarithmic, exponential, and others found in science and engineering. Among
its features are 1) an unusually large number and variety of functional forms
to which it will fit data, 2) the speed which comes from being a compiled
program in Turbo Pascal, 3) the support of the 8087 math coprocessor in the
case of LSTSQR87, 4) a wide variety of measures of the quality of the fit
provided, including 95% confidence intervals, 5) the capability of graphing
the results of a fit, and 6) a high degree of interactive flexibility, which
allows multiple fitting attempts for a given set of data with changes in data
points and fitting functional form between fitting attempts and the fitting of
an unlimited number of sets of data, all without leaving the program.
