GENBLIS (GENetic optimization and Bootstrapping of LInear Structures) is an
evolutionary program which estimates structural equation models with latent
variables by combining the global search strength of evolutionary
algorithms with the ability of derivative based algorithms to do rapid
local hill climbing. GENBLIS provides bootstrap confidence intervals for
parameters and bootstrap confidence limits for the goodness-of-fit test
statistic. Structural equation models are often used in political science,
sociology, psychology, marketing and related social science fields to
specify and estimate stochastic models for linear relations in the presence
of measurement errors.

There are a variety of ways to parameterize structural equation models. Following Bollen (1989 ), GENBLIS uses a parameterization developed by Jöreskog (1973 ) and Wiley (1973 ). This parameterization has become a standard because of the popularity of the LISREL program which was developed by Jöreskog and Sörbom.

GENBLIS is described in the GENBLIS Manual. One can download the following binaries:

GENBLIS is described in the GENBLIS Manual. One can download the following binaries:

- AIX
1.11.4.

- HP-UX
1.11.4.

- LINUX
1.11.4.
This version does not require dynamic access to any libraries. All of
the required functions are linked into the binary. It ought to work
with most any LINUX system.

- Windows 95/98/NT
1.11.4.
The program is packed using the zip format.

The UNIX binaries are in tar and gzip format. Therefore, to unpack them
in a given directory please issue the following commands:

`zcat genblis.linux-1.11.4.tar.gz | tar -xvf -`

You may have to change the mode of the `genblis` binary to make it
an executable. The can be done by issuing the following command:

`chmod ugo+rx genblis`

Small parts of the current GENBLIS code were adapted from an early version of Zbigniew Michalewicz's GENOCOP I.
