INTRODUCTION
|
|
======================================================================
|
|
Thank you for your interest in CurveExpert 1.3!
|
|
|
|
CurveExpert 1.3 is a comprehensive curve fitting system for Windows.
|
|
XY data can be modelled using a toolbox of linear regression models,
|
|
nonlinear regression models, interpolation, or splines. Over 30 models
|
|
are built-in, but custom regression models may also be defined by the
|
|
user. Full-featured graphing capability allows thorough examination of
|
|
the curve fit. The process of finding the best fit can be automated by
|
|
letting CurveExpert compare your data to each model to choose the best
|
|
curve. This program was designed to be simple but powerful, so that all
|
|
users can obtain a model for their data quickly and easily.
|
|
|
|
Documentation is provided in the form of a Windows help file. This
|
|
on-line manual is complete and does not need the supplement of a
|
|
printed copy. This way, we conserve our Earth's valuable resources
|
|
while at the same time reducing the cost of this software.

IF THE INSTALLATION PROGRAM FAILS WITH A GPF (16-bit version only)

INSTALLATION
|
|
======================================================================
|
|
If you obtained this program from an Internet source, you must first
|
|
unzip CVXPTxxx.ZIP (using PkUnzip or WinZip -- if you don't have this,
|
|
go back to your ftp site and pick it up) to unpack all of the
|
|
distribution files. Note that the xxx denotes the version number of
|
|
CurveExpert that you have obtained (eg. version 1.21 will be cvxpt121.zip).
|
|
From the Program Manager, File Manager, or your particular shell, select
|
|
File|Run and run the SETUP.EXE program that was included in your
|
|
CurveExpert distribution.
|
|
|
|
The installation program will ask you where to install this software
|
|
and give the space requirements required. Also, you may give your
|
|
name and company, if you are a registered user. The rest of the process
|
|
is automated -- CurveExpert will install itself onto your computer in
|
|
the location you specified and will make its own Program Manager group.
|
|
|
|
Should you ever want to uninstall CurveExpert, simply double-click
|
|
on the UnInstall icon in the CurveExpert program manager group. In
|
|
Windows 95, go to the Control Panel|Add/Remove Hardware applet to
|
|
