Nonlin 3.1 <ASP> - Nonlinear regression statistics and curve fitting
1-DATA MAR94 NONLINEAR REGRESSION STATISTICS PLOT CURVE FIT
FILES: nonlin31.sdn
Author: Phillip H. Sherrod
Registration: $45
Nonlin performs linear and nonlinear statistical regression analysis.
Nonlin determines 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, logistic, and
general nonlinear equations. You specify the form of the equation
using normal algebraic notation. Nonlin includes a rich set of
built-in library functions such as trig, probability, exponential,
log, Bessel, etc. that you can use in the equation being fitted to the
data.
In addition to fitting the equation to the data, Nonlin determines a
variety of statistics including confidence intervals, t and F
statistics, and Durbin-Watson test for autocorrelation. Nonlin can
also plot the data and fitted equation.
Nonlin includes a 60 page manual that explains regression analysis and
gives many examples.
Nonlin is the best and most powerful shareware regression program
available. It is in use at many labs and universities around the
world.
