ITALASSI v1.1
Interaction Viewer

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   info@provalisresearch.com

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:
