ITALASSI is a freeware program that has been written to facilitate
interpretation of regression models (2 independent variables) with an
interaction term. The program allows you to enter several regression
models (two bivariate, one multiple additive, and one multivariate with
interaction) in the form of equations or compute those equations from
raw data and displays the various models using 2D and 3D graphs. The
program may also be used in advanced stat courses to illustrate statistical
interactions or applied multiple regression.
If you have any comment or suggestion for possible improvements
or additional features that would be useful both for research
or teaching purpose, send us a message at

EXAMPLES NEEDED
We would like to offer with the program a large library of regression
examples in various area, illustrating various types of interaction,
problems, etc. So if while experimenting with the program, you
find interesting findings or good examples and would like to share
those finding with others users (teachers, students, and researchers),
just send us a copy of the .EQU file you created and an authorization
to distribute this sample file with the program. (Our preference
is for real data, so a reference to the initial research project
would be very much appreciated).
While the current version is free and will remain a freeware, those
who will contribute by providing examples will also be allowed to use
any enhanced version for free.
INFORMATION ABOUT THE PROGRAM
The program runs under Windows 3.1 or later and requires about 550K
of disk space. To download the program, click on the following links:
