PC-NORMIX is distributed with the following files:

C:\NORMIX21:   The directory where you should store all these files.

DOCUMENTATION:
   readme      This file.
   normix.doc  Documentation for the user.
   license.txt The license agreement and form for you to register your use.

SOURCE:
   pcnormix.for  The FORTRAN source program.


EXECUTABLE CODE:
   pcnormix.exe   Version 2.1 for 386 or above.

   DOSXMSF.EXE    This is the DOS extender. PLEASE COPY IT INTO A DIRECTORY
                  THAT IS IN YOUR PATH. It must be in your path.

   DOSXNT.386     Required for Windows operation. In C:\WINDOWS\SYSTEM.INI
                  in the [386ENH] section, please add the statement:
                  DEVICE=C:\NORMIX21\DOSXNT.386. (This assumes that you
                  are naming this NORMIX directory C:\NORMIX21.)
 
INPUT-FORM TEMPLATE:
   form.inp     This file should only be copied, never written on.
   thisjob      A default input-form filled in with the Fisher Iris problem.

SAMPLE PROBLEM INPUT-FORMS (stored in the \SAMPLES subdirectory):
   artif.inp    Artificial clusters with unequal covariance matrices. This
                file also contains the data for the problem.
   irismap.inp  The Fisher Iris problem with equal covariance matrices.
   irismix.inp  The Fisher Iris problem with unequal covariance matrices and
                initial estimates supplied by the user.
   svib.inp     The Strong Vocational Interest Blank problem described in
                Wolfe (1978). Multivariate Behavioral Research, 13, 33-44.
   thisjob      The same as irismap.inp. This file name is the default when
                the user does not specify an input-form file at the keyboard.


SAMPLE PROBLEM INPUT DATA (stored in the \SAMPLES subdirectory):
   iris.dat     The data for the Fisher Iris problem, specified by irismap.inp,
                irismix.inp, and thisjob sample input-forms.
   svib.dat     The input data specified by svib.inp.


SAMPLE PROBLEM ANSWERS (stored in the \ANSWERS subdirectory):
   These are the answers to the sample problems, generated by my computer.




BATCH FILES:
    normix.bat     A batch program that bypasses interactive operation
                   of pcnormix.exe and redirects I/O to files specified on 
                   the command line.
                   Usage: "normix samples\svib svib.see"  would take the 
                          input-form from samples\svib.inp and store the screen 
                          output on the file svib.see. This second argument is
                          optional.
    examples.bat   An illustrative batch file that runs all of the sample
                   problems. The user should be able to write similar batch
                   files for running a large number of problems overnight
                   on in the backgound under Windows.
\YOURRUNS:
     This directory is initially empty. After running EXAMPLES, the
     directory will contain the results of sample problems run on your
     machine. These can be compared with the results stored in \ANSWERS.
     It is recommended that the user not only run the EXAMPLES batch file,
     but also try running pcnormix.exe interactively with the sample
     problems in order to become familiar with the program's operation.
________________________________________________________________________________
Running under Windows: 
     PC-NORMIX is basically a DOS program that uses extended memory. 
     I have successfully run it as a DOS window under Norton Desktop for
     Windows 3.1. The file NORMIX.ICO is an icon for for the file WNORMIX.BAT.
     If you can't get this to work, you could probably go the the Windows FILE
     menu and click on RUN, then type in c:\normix21\wnormix your.inp.
