Richard Palmer-Jones<richard.palmerjones@gmail.com>: There are a variety of ways to loop over categories and collect results, but note that the approach you give does not agree with the results of -svy:mean- (check your CIs), and does not collect the values of categorical variables (e.g. NE and E both become E). My question stands--what do you want this for? The goal dictates the preferred method. For example, if you wanted to write out a formatted table, an easy way to go is to use -estout- e.g. use nhanes2, clear la def smsa 1 "City" 2 "Noncity SMSA" 4 "NonSMSA" la val smsa smsa egen subpop=group(smsa region), label svy: mean bpsystol, over(subpop) nohe noleg qui ta subpop, gen(i_) label qui svy: reg bpsystol i_*, nocons eststo smsa esttab smsa, nogap varw(25) la b(%9.4f) ci(%9.4f) nostar or to an MSWord file: esttab smsa using t.doc, rtf nogap varw(25) la b(%9.4f) ci(%9.4f) nostar On Fri, Jul 10, 2009 at 11:24 AM, Richard Palmer-Jones<richard.palmerjones@gmail.com> wrote: > Sorry, I was taking a short cut - yes I want the ses - my problem > was/is to access the e(over_labels) which consist of two comonents > separated by a space. > > So to add ses I can > > ..... > mat ev = vecdiag(e(V))' > mat eb = e(b)' > mat en = e(_N)' > mat evn = eb,ev,en > > drop _all > svmat evn > gen row = "" > forval o = 1/`c(N)' { > local r : label g `o' > replace row = "`r'" in `o' > } > gen var1 = substr(row, 1, 2) > gen var2 = substr(row, -1, 1) > gen lb = evn1 - invttail(evn3-1,0.025) * (evn2^0.5 * sqrt(evn3) / sqrt(evn3)) > gen ub = evn1 + invttail(evn3-1,0.025) * (evn2^0.5 * sqrt(evn3) / sqrt(evn3)) > > gives me the ses > > But I am disappointed I cannot captuer the over_labels in am ore > elegant way, and was just thinking there must be a way to parse the > e(over_labels) macro in a better way. but the spaces between "NE and > "1`" were defeating me until I came upon the "local r : label > labelname # " wheeze. > > So, expecting enlightenment > On Fri, Jul 10, 2009 at 3:02 PM, Austin Nichols<austinnichols@gmail.com> wrote: >> Richard Palmer-Jones<richard.palmerjones@gmail.com>: >> >> I don't understand--if indeed you only want the weighted means and not >> the SEs, then use -collapse- and get there in one line, and note that >> pweights and aweights are equivalent if you do not need SEs.
