I guess that, for consistency with pther cpmmands (ols for example), we ought to run PCA on an automatically trimmed dataset if there are missing observations in the currently selected sample, and duly indicate this in the output. OTOH, I also think that our pca apparatus needs some tweaking: for example, there is no GUI equivalent to the --save=n option, and that we also should introduce a --varimax option for saved factors (and possibly --quartimax). Perhaps we could get these done after release. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
