When running STATGRAPHICS for the first time, it stores important information in your system's registry. This requires that you be running as an administrator. If you are using Windows Vista, you must click on the STATGRAPHICS desktop icon with the RIGHT mouse button and select "Run as administrator" in order to have the proper access to the registry. If your organization limits administrator access to the IT department, you must have them run the program the first time (and later if your enter an activation code). After that, administrator rights are not required.

When installing the program, it must be done using the computer on which the program will be run (unless you have purchased the special network version). During installation and during the first execution of the program, you must have write access to the registry. If you install it without write-access to the registry, or copy the program files from another computer without running the installation program, the license information will not be placed in the proper location in the registry. To correct this, use regedit.exe to add the following key to the registry:

   HKEY_LOCAL_MACHINE
      SOFTWARE
         Statgraphics
            STATGRAPHICS Centurion XV
               15.2.0.0

It should then run properly.

One of the features of the StatWizard is the ability to create analyses automatically for each level of a selected variable. Load your data into a datasheet and invoke the StatWizard by pressing the wizard's cap on the main  toolbar. On the first dialog box, choose "Select Analyses Based on Type of Data." Specify the variables to be analyzed on the second dialog box. On the third dialog box, select "Each Unique Value of" and enter the name of the "BY" variable. The desired analyses will be run at each level of that variable and placed into a separate window.

The easiest way to transform data is "on-the-fly". On any data input dialog box, you can type an expression such as "LOG(column name)" where you would normally enter the name of a column.  This will transform your data for the current analysis without disturbing the datasheet. Alternatively, highlight an empty column in a datasheet and select "Generate Data" under "Edit" on the main menu. You can then enter the desired expression and have the transformed data placed in that column.

You should select the One Variable Analysis procedure and enter the following expression in the Data field: REP (X,Frequency). This will expand the data column so that each value of X occurs with the corresponding Frequency and gives you the results you desire. This type of expansion works in any procedure.

Both the Six Sigma menu and the standard menu access the same set of statistical procedures. The only difference is the organization of topics on the main menu. The Six Sigma menu arranges topics under the DMAIC headings (Define, Measure, Analyze, Improve, Control) used in Six Sigma, while the standard menu follows the normal STATGRAPHICS structure. You can switch between the two menu structures by accessing "Preferences" on the "Edit" menu.

Leave the serial number field blank if you are installing a 30-day evaluation version.
