Michael, you can also use -regsave- to save confidence intervals to a dataset. You can install -regsave- with the command -ssc install regsave, replace- ***************************************** sysuse auto, clear svyset rep78 [pw = turn] svy, subpop(if foreign==0): total trunk regsave, ci list ****************************************** Julian On Jul 29, 2011, at 1:33 AM, statalist-digest wrote: > Date: Thu, 28 Jul 2011 17:56:02 -0400 > From: Steven Samuels <sjsamuels@gmail.com> > Subject: Re: st: saving the confidence interval as a scalar > > Michael, try the following: > > ***************************************** > sysuse auto, clear > svyset rep78 [pw = turn] > svy, subpop(if foreign==0): total trunk > matrix b = e(b) > scalar tot = b[1,1] > matrix v=e(V) > scalar v =v[1,1] > scalar bound = /// > sqrt(v)*invttail(e(df_r),0.5*(1-c(level)/100)) > scalar ll = tot-bound > scalar ul = tot + bound > di c(level) "% Confidence Interval" _newline /// > "Estimate: " %8.0fc tot /// > " ["%7.0fc ll "," %8.0fc ul "]" > ****************************************** > > On Jul 28, 2011, at 12:12 PM, Monuteaux, Michael wrote: > > Hello everyone, > > I am estimating various parameters using a survey dataset.

But, I would like to also save the upper and lower confidence interval bounds as scalars, as well. Is it possible to access these values as scalars or a matrix? * * 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/
