You've got much more than that going on. -diagt- calls -diagti- which calls many other things, and so on. Somewhere along that chain, matrices are being cleared. It's not your problem below, but I did notice that -diagt- overwrites any existing matrix called T. As it destroys such a matrix any way, that's incidental, but using a temporary name would be widely considered better practice. Nick n.j.cox@durham.ac.uk moleps I´m creating a table using diagt (available from ssc) for different cutoff values of p. However the matrix is lost after calling diagt (version 2.0.5) and the same happens using this example-code: (stata v10.1) (ssc install diagt) sysuse auto.dta gen ind=price>10000 diagt ind foreign mat a=(r(sens),r(spec)) mat list a diagt ind foreign mat dir viewsource diagt.ado --no reference as far as I can tell to dropping of matrices...Neither with diagti. There is a previous post with diagt for bootstrap purposes, but there is no reference to dropping of matrices. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
