- 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.

- 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.
