Program: FIT2

Program type: Engineering, curve fit
Special requirements: CGA or emulation [HGCIBM worx]
1 liner:
FIT2 fits equations to your data by least squares.
FIT2 fits assorted curves to X,Y (two dimensional) data. The equations handled
are: Linear regression, Exponential regression, Geometric regression,
Logarithmic regression, and Polynomial regression,
Data may be entered from the keyboard or read from a data file. Only random
access (fixed length fields) files are supported. Irrelevant fields & records
may be ignored. Data may be subjected to various pre-treatments.
Graphs of the data and the fitted [fat?] curve are plotted on screen. The
calculated coefficients and residuals are displayed. Interpolation and
extrapolation are conviently handled by shuffling the whatzit to the proper
location.
The most surprising feat is that FIT2 managed to print the graphic plot on my
Apple II vintage Seikosha SP-1000A printer.
Documentation: Documentation is adequate, without being obese. Occasional
mispellings and typograhpical errors may be attributed to American English most
likely being the author's third language.
Source code: FORTRAN?
