WOMBAT is a program
to facilitate analyses fitting a linear, mixed model via restricted
maximum likelihood (REML).
It is assumed that traits analysed are
continuous and have a multivariate normal distribution.
WOMBAT is set up with quantitative genetic analyses in mind, but is
readily applicable in other areas. Its main purpose is the estimation
of (co)variance components and the resulting genetic parameters. It is
particularly suited to analyses of moderately large to large data sets
from livestock improvement programmes, fitting relatively simple
models.

wombat32gen.tar.gz `Generic' Linux 32-bit version, does not
assume a Pentium IV processor, like wombat32lf95 otherwise; try this
version if the others cause problems. Size 1,022 KB, 795 downloads (since June
1, 2007), last update: 20/11/09.
wombat32check.tar.gz Linux 'debug' version - use for both 32-
and 64-bit systems to compile a bug report (see Chapter 3.3 of the
manual). Size 2.39 MB,
585 downloads (since June 1, 2007), last update: 20/11/09.
wombatwin.tar.gz

wombatwin2.zip - new & little tested
Windows 32-bit version compiled under MinGW; like wombatwin.tar.gz
(Compilation notes) but
does not require Cygwin.
Size : 1.19 MB,
2670 downloads (since June 26, 2007), last update: 25/03/09.

Note for Windows users: The files in the Example directories are Linux files.
Linux and Windows differ in the `end-of-line' codes used. There appear to be no inconsistencies
with the Cygwin environment. However, when using wombatwin2.zip `directly' under Windows, you may
need to convert the files provided; look for a tool like like `unix2dos' !
