Linear and Nonlinear Statistical Regression Analysis
Phillip H. Sherrod
Member, Association of Shareware Professionals (ASP)
Nonlin performs statistical regression analysis 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 $25 for shipments in the USA or $30 for
shipments outside of the USA. Registered users receive a
registered version of the program, a laser-printed, bound
manual, and three months of telephone 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
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. However, Nonlin may not be sold, or
incorporated in another product that is sold, without the
permission of Phillip H. Sherrod. 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.
