*** NONLIN -- Nonlinear Regression Analysis Program ***

Nonlin allows you to perform statistical regression analyses to estimate the
values of parameters for linear, multivariate, polynomial, and general nonlinear
functions. The regression analysis determines the values of the parameters
which cause the function to best fit the observed data that you provide. Nonlin
allows you to specify the form of the function whose parameters are being
estimated using ordinary algebraic notation. In addition to determining the
parameter estimates, Nonlin can be directed to generate an output file with
predicted values and residuals. It can also plot the observed values and the
estimated function and the residual values. In addition to performing
regression analysis, Nonlin can also be used to find the root (zero value point)
or minimum absolute value of a nonlinear expression.

Nonlin is a "shareware" product. You are welcome to make copies of this
program and pass them on to friends or post this program on bulletin boards
(in its original, unmodified form).

As a shareware product, you are granted a no-cost, trial period of 30 days
during which you may evaluate Nonlin. If you find Nonlin to be useful,
educational, and/or entertaining, and continue to use it beyond the 30 day
trial period, you are required to compensate the author by sending the
registration form printed in the REGISTER.DOC file with the appropriate
registration fee to help cover the development and support of Nonlin.

In return for registering, you will be authorized to continue using Nonlin
beyond the trial period and you will receive the most recent version of the
program, a laser-printed, bound manual, and three months of support via
telephone, mail, or CompuServe. Your registration fee will be refunded if
you encounter a serious bug that cannot be corrected.

Nonlin requires 512 KB of memory. In order to use the opional PLOT command
you must have a CGA, EGA, or VGA monitor. An 80x87 numeric coprocessor
greatly improves its execution speed, but is not required. Nonlin has been
successfully run on dozens of computer types ranging from 8088's and laptops
to 486's. However, one user reported that it "hung up" while running on a
Gateway brand computer. The author would appreciate receiving information
about any computers on which Nonlin does not successfully operate.

The Nonlin system consists of the following files:

NONLIN.EXE -- The executable program.
NONLIN.DOC -- Documentation file.
REGISTER.DOC -- Form to register and order latest version of Nonlin.
NONLIN.FON -- Font file used if you request a plot.
NONLIN.LJF -- HP LaserJet font file used if you print a plot.
*.NLR -- Example command files.

To install Nonlin, copy the files into the directory of your choice. If you do
not plan to generated hard copy output for a LaserJet printer, you may delete
the NONLIN.LJF file. If the NONLIN.FON and NONLIN.LJF files are not in your
current directory, you must place a command of the following form in your
AUTOEXEC.BAT file to tell Nonlin where to look for its font files:

SET NONLIN=directory

Where "directory" is the name of the device and directory where the files are
located. For example, if the files are located in a directory named NONLIN on
the C disk, the following command could be used:

SET NONLIN=C:\NONLIN

Once Nonlin has been installed, it can be started using a DOS command
of the form:

NONLIN command_file

where "command_file" is the name of a file containing Nonlin commands that
control the analysis.

If you are anxious to try Nonlin, run some of the examples by using
the following commands:

NONLIN F33YEAR
NONLIN F33EXP
NONLIN MAGNET
NONLIN COOLING

Read or print the NONLIN.DOC file for further information.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
