OK, thank you for your responses, but my question was not enough precise :
I want to realize a factor analysis based on the tetrachoric coefficients matrix WITH STATA. The Stata program tetrac (author : Philip B. Ender) permit to create this matrix, but I don't know how realize WITH STATA a factor analysis on a such matrix (the factor Stata program don't permit to use a correlation matrix different of the classical (pearson rho coefficients) correlation matrix). The procedure "factor" of SAS, for example, permit to choose a dataset as the working correlation matrix in defining
the dataset as a correlation matrix.

>Dear Jean-Benoit,
> You might review the PRELIS and LISREL options for performing a factor analysis based on a polychoric and/or polyserial correlation matrix. They are marketed by Scientific Software Incorporated. The web site URL is http://www.ssicentral.com .
