- Nonlin performs statistical regression analysis and curve fitting
- to determine the values of parameters for an equation, whose form
- you specify, that cause the equation to best fit a set of data
- values. Nonlin can handle linear, multivariate, polynomial,
- exponential, and general nonlinear equations. You specify the form
- of the equation using ordinary algebraic notation. In addition to
- determining parameter values, Nonlin computes confidence intervals
- and other statistics. The data values and fitted equation can be
- plotted. Nonlin can also be used to find the root of a nonlinear
- equation. Nonlin is the most powerful shareware regression program
- available.
-
- Hardware requirements: IBM PC compatible computer with at least
- 512KB memory. A CGA, EGA, or VGA display adapter is needed only if
- a plot is requested. A numeric coprocessor is used if it is
- present but is not required.
-
- Nonlin is a shareware program. Users are granted a 30 day trial
- use. If it is used beyond the trial period a registration fee must
- be sent to the author. The registration fee is $45 for shipments
- in the USA or $50 for shipments outside of the USA. Registered
- users receive a registered version of the program, a bound, typeset
- manual, and three months of support. The registered version of
- Nonlin omits the startup shareware notification screen and provides
- the ability to print plots on LaserJet printers.
-
- 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, CD ROMS, or other means
- provided the entire Nonlin distribution is included in its
- original, unmodified form. A distribution fee may be charged for
- the cost of the diskette (or CD ROM), shipping and handling.
- Vendors are encouraged to contact the author to get the most recent
- version of Nonlin. The registered version of Nonlin is not
- shareware and may not be redistributed.
