The parameterization of the units at levels 2 and above is by Cholesky decomposition of the error covariance matrix. For a single factor, this means the standard deviation of the factor: . di 3.7773108^2 14.268077 -- Stas Kolenikov, also found at http://stas.kolenikov.name Small print: I use this email account for mailing lists only. * * 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/
