Nonlinear Statistical Regression Analysis Program

Nonlin performs statistical regression analysis 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. You 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 data
observations and the computed function. Although designed for
regression analysis, Nonlin can also be used to find the root
(zero point) or minimum absolute value of a nonlinear expression.
Nonlin is in use at many engineering and research centers around
the world.
SUMMARY OF MAIN FEATURES
. Fits general equation to data values.
. Form of equation is specified using normal algebraic
notation.
. A library of built-in function is included for use in
specifying the equation. The built-in functions include
trig, exponential, log, Bessel, elliptic integrals, and many
others.
. Nonlin handles multivariate functions; up to 12 parameter
values may be estimated.
. A "SWEEP" command allows you to specify a range of starting
values in case the function has both local and global
minimums.
. Student's `t' statistic and associated probability is
computed for each estimated parameter providing an estimate
of the significance of the value.
. Confidence intervals can be computed.
. Other statistics are computed including `F', coefficient of
multiple determination, and Durbin-Watson.
. The data and fitted equation can be plotted in high
resolution on the console or a HP LaserJet printer.
. Nonlin can be used to find the root, or point of minimum
absolute value, of a nonlinear function.
. Nonlin uses a state-of-the-art "adaptive" nonlinear
minimization algorithm that is as good, or better, than you
are likely to find in even the most expensive nonlinear
regression packages.
SYSTEM REQUIREMENTS
Nonlin will run on any IBM PC compatible computer under MS-DOS
version 3.0 or higher. A minimum of 500K of free RAM is
necessary (less if LaserJet plotting is not performed).
The program does not need a numeric coprocessor but will use it
if available. A coprocessor is highly recommended for large
analyses.
