DDEfit 0.504
Posted 18/3/2003.
What's new
and what's fixed in this version.
This page contains the files needed to use the
DDEfit
program. This is a
Windows 9*/NT based package for fitting (delay) differential equations and
discrete time models to data. It is written for the purpose of fitting
ecological process models.
The software is provided under the following conditions:
- No part of it may be used or sold for profit.
- It may not be distributed or re-distributed without full
acknowledgement of authorship.
- Absolutely no warranty of any kind is provided, and nothing in the
code or documentation over-rides this.
Please read this before downloading:
GNU General Public License
.
You will need a GNU, Borland or Microsoft C/C++ compiler capable of
producing Win9*/NT 32 bit multi-threaded GUI applications. I used
Microsoft Visual C/C++ 6 and an excellent port of gcc (see
below for link)
Please drop me an email if you download and use this package. My address
is simon@stats.gla.ac.uk
The reference for methods implemented in
this code is Wood, S.N. (2001) "Partially Specified Ecological
Models" in press Ecological Monographs 71. See
preprints page
for a pre-print.
The basic concept was first suggested in the discussion of: Wood,
S.N. (1994) "Obtaining birth and mortality patterns from structured
population trajectories" Ecological Monographs 64(1):23-44.
DDEfit is open source. The package
contains a fair number of files, so they are provided in a zipped archive:
-
ddefit504.zip
- Please let me know if you have any problems installing or using
DDEfit
: it's intended to work, so I'd like to know if it doesn't! My
email is: simon@stats.gla.ac.uk
If you want to use gcc you need to
have a version of the compiler capable of compiling to 32 bit native
windows applications. Several are available. The one that I have used is
EGCS Mingw32 Native.. It's stand alone and comes with gcc ,
a resource
compiler windres, and a debugger gdb. To learn about GNU
C for Win32
(including other versions of the compiler), try the
gcc for
Win32 page.

Bugs
Please email me with bug reports and I'll try and fix them. To facilitate
bug fixing I need to be able to reproduce the problem, so it's really
helpful to have the model definition file, data file and weight file (also
any parameter file that might be needed) that causes the problem, along
with a description of what to do to cause it to happen. Any models and
data sent for this purpose will be treated as confidential and used only
for debugging!
(Please let me know about non- reproducible bugs as well, so that I can
keep
an eye out for possible causes of them).
