- *** 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.
-
- A "DEMO.BAT" file is included to run several example analyses.
-
- There are two versions of the Nonlin program: shareware and registered. You
- are welcome to make copies of the shareware version of Nonlin and pass them
- on to friends or post this program on bulletin boards or distribute it via
- disk catalog services provided the entire Nonlin distribution is included
- 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 a registered 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.
-
- The registered version of Nonlin omits the shareware notification screen
- at the start of the run and does not require you to press a key to proceed
- with the analysis. The registered version also includes the ability to
- print plots on HP LaserJet printers.
-
- 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.
-
- 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 (registered version only).
- *.NLR -- Example command files.
- DEMO.BAT -- DOS batch file to run several demo regressions
-
- To install Nonlin, copy the files into the directory of your choice. The
- registered version of Nonlin includes a file named NONLIN.LJF with the
- fonts needed for printing plots on HP LaserJet printers. 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, a DOS batch file named "DEMO.BAT" is
- included which runs several example analyses. To run it simply type the
- command:
-
- DEMO
-
- You can also run examples by entering the following commands:
-
- NONLIN AIDS
- NONLIN F33YEAR
- NONLIN F33EXP
- NONLIN MAGNET
- NONLIN COOLING
-
- Read or print the NONLIN.DOC file for further information.
