- 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.
