Software for Latent Variable Models

The program GENLAT is available for free from http://www.bristol.ac.uk/cmm/publications/aimdss-2nd-ed/downloads.html. The program fits a one- and two-factor latent trait model to binary, nominal, ordinal and metric manifest variables and a latent class model to binary and nominal manifest variables.

The program LTM is available for free from http://www.jstatsoft.org/v17/i05. It is available as an R version and S-Plus version. ltm fits the linear one- and two-factor models but also allows for inclusion of nonlinear terms (e.g., interaction and quadratic terms).  Extra features: computation of factor scores using Multiple Imputation for model with non-linear terms, Rasch model for which Goodness of Fit is assessed using a parametric Bootstrap version of the Pearson chi-squared, and some more that you can find in the manual.
