I've finally gotten around to making the GENINT program available. Basically, the GENINT program is a SAS (tm) program which takes, as input, a PROC CALIS structural equation model for exogenous variables, and then produces, as output, a  CALIS program for quadratic effects or for interaction effects at the latent variable level.

In addition, this program can also be used to generate the nonlinear constraints for quadratic and interaction effects in a compact form, so that you, the user, only have to look at latent variables which reflect the latent variables you are interested in and don't have to mess around with the ``nuisance" cross-product terms in the original Kenny & Judd model.

Perhaps the easiest way to introduce the actual use of the program is to walk you through a few examples. The buttons below will show you two examples of the GENINT program and then introduce you to variations on the quadratic and interaction models given in the original Kenny & Judd article. I've written an introduction to the use of the genint program for the Kenny & Judd models here and will stop here tonight. I've added some examples of the Kenny & Judd models with alternate possibilities.

 I've just now put this material up for folks to look at, so if there are any questions and suggestions about this, please e-mail me at: woodpk@missouri.edu.
