One possibility is to use the -parmest- and -lincomest- packages, both
downloadable from SSC. The -lincomest- package is like -lincom-, but
saves the results as Stata estimation results. And the -parmest- package
inputs a set of estimation results and creates an output dataset (or
resultsset) with 1 observation per estimated parameter and data on
parameter names, estimates, confidence limits, P-values and other
parameter attributes.
For an example of the use of -parmest- and -lincomest- together, see
Subsection 3.3 of Newson (2003).
I hope this helps.
Best wishes
Roger

I am using lincom to combine 3 estimates:
lincom(1.District1+1.District2+1.District3)/3
the output table gives the combined estimate and its confidence intervals. However, typing ereturn list and return list I get everything but I do NOT see the confidence interval limits anywhere! (I get the standard error in r(se) and the estimate in r(estimate)).
Please help! What I'd like to do is to write the confidence interval limits to a matrix that I'm creating inside a foreach loop which I will later display.
