Re: st: Re: -svy: mean - problem with returned matrices

[Steven Samuels <ssamuels@albany.edu>]

Nick, Stas, Michael, Richard:  Thanks for your quick responses.  The  
problem (i.e. bug) is not confined to -display-.   I also could not  
not use "el(e(b),1,1)" as an expression in -generate-  or -local-. I  
guess it's time for me to buckle down and learn Mata;  meanwhile,  
Michael and Richard's solution is all I need.
