ADDITIONAL DOCUMENTATION FOR M.V.S.P.
VERSION 1.3 (Released Feb., 1986)
This distribution disk of MVSP, A Multivariate Statistical
Package, should contain the following files:
READ.ME - The file you are now reading
MVSP.COM - The MVSP program itself
MVSP.000 - Overlay file needed for the MVSP program
MVSP.DOC - Full documentation
JOLIMOSI.DAT - Example data file
GAUCH.DAT - " " "
REFORMAT.COM - Utility for reformating data files
REFORMAT.PAS - Source code for REFORMAT
When you first receive this disk, you should make a backup of
the disk, and then print out the manual. The file MVSP.DOC is
already formatted, so that it may be sent directly to your
printer. This is most easily done by entering the following
command at the DOS prompt:
COPY MVSP.DOC LPT1
The manual describes the operation of the program and gives
some specifics about how these procedures are computed. It does
not, however, attempt to teach you about how these procedures
should be used, nor does it dwell on the assumptions and
derivations of the techniques. It does, however, have a
reference list of sources which I have found useful in studying
these techniques. If you are not already familiar with these
procedures, I urge you to spend some time learning about these
procedures and the assumptions they make about the data.
Also please read the section on the User Supported Concept.
This program is being distributed as user supported software. If
you find this program to be of value, you are encouraged to send
a voluntary contribution ($25 suggested) to support further
programming efforts. I will notify all registered users of
updates to the program and they will be entitled to new versions
for only the cost of distribution. Registered users may also
obtain a version of the program compiled for the 8087 math
coprocessor, which speeds up the calculations greatly.
Whether you register or not, you are still encouraged to copy
and distribute this program. Thank you!
REFORMAT.COM
============
The program REFORMAT.COM is a utility I've written to convert
data files between the MVSP format and the compressed format used
by DECORANA. DECORANA is a detrended correspondence analysis
program developed by M.O. Hill and distributed by Hugh G. Gauch
(see Hill & Gauch, 1980, ref. in MVSP manual). It was written in
FORTRAN for various mainframe computers, but I've recently run
accross a version which was adapted for the IBM PC by Christopher
Clampitt (Department of Botany, Univ. of Washington, Seattle, WA
98195).
DECORANA uses a compressed data file format in which only
non-zero abundances are included. Rather than reformatting and
rewriting my data matrices by hand every time I run them through
DECORANA, I wrote a utility to quickly convert them. I'm passing
it on to MVSP users with the assumption that many people who use
MVSP will also be interested in using DECORANA.
This reformatting utility is run by type the following
command at the DOS prompt:
REFORMAT infilename [outfilename]
where 'infilename' is the name of your input file and
'outfilename' is the name of the new file for the converted
matrix. If 'outfilename' is not specified, then the input file
name is used, with a new extension, '.RFM'.
If REFORMAT finds an MVSP file header (discussed in MVSP
manual), then it will convert this file to DECORANA format, after
asking whether the DECORANA file should be set up for an octave
transformation (see DECORANA documentation). If the MVSP file
header is not found, it will assume that the input file is in the
proper format for DECORANA, and will convert it to MVSP format.
If the file is not in the correct format for DECORANA, the
results will be unpredictable (but you will probably get a
numeric format error). Note that, due to the lack of built in
formatting capabilities in the read procedure in Pascal, the
format statement in the DECORANA file is not followed. Instead,
the data are read in free format, so that data elements must be
separated by spaces. I hope to correct this in a future version
of this program. The labels, however, are read in a A8 format,
so that they need not be separated by spaces.
I've included the Turbo Pascal source code for REFORMAT, so
that you can see how it works and so that you can modify it if
you wish. Note that this is written using some features specific
to the Version 3 compiler, particularly the command line
parameter parsing function PARAMSTR. This program will not
compile under the Version 2 compiler.
If you find any bugs in the program, or you you come up with
a particularly ingenious modification, I would appreciate if you
would contact me and tell me about it. All I ask is that you do
not distribute modified versions of this program. Thanks.
