CurveExpert 1.3: A comprehensive curve fitting system for Windows
Copyright (c) 1995-1997 Daniel Hyams

======================================================================
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.
For the information on the latest features of CurveExpert, visit the
CurveExpert home page at

This software package is ShareWare.
SUPPORTED PLATFORMS
=====================================================================
CurveExpert has been released for the following platforms:
16-bit version: Windows 3.1 or later
32-bit version: Windows 3.1 or later + Win32s 1.30 or later
Windows 95
Windows NT 3.51 or later
Note that the 16-bit version is Windows 95 compatible, so it will
run under Windows 95 as well as Windows 3.1.
IF THE INSTALLATION PROGRAM FAILS WITH A GPF (16-bit version only)
=====================================================================
If the installer program fails with a General Protection Fault,
please restart Windows immediately. CurveExpert has been installed
correctly, and will run correctly once Windows has been restarted
after a fault of this type by the installer.
REGISTRATION -- HOW TO REGISTER
======================================================================
To order CurveExpert, open the help file by choosing 'Help' from the
Help menu. Then click the 'Register' button in the help file. This
will give directions for ordering CurveExpert as well as the order
form. The registration fee of $35 [16-bit version] or $40 [32-bit
version] can be submitted via mail or by a credit card.
Development of this software has taken countless hours of study,
programming, and debugging. Please support the shareware concept
and register the software if you intend to keep and use it! The
future of this product depends on the response that I receive from
you, the user. If you would like for this project to continue and
grow, please send suggestions and register, if you use this program.
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
uninstall CurveExpert.
