st: Survey standard errors of grouped data proportions |

I am using Stata 13.1 SE on a Windows 7 platform. I have complex survey design data set, with replicate weights, etc and have successfully svyset using the statement svyset _n [pweight=3Dwgt], vce(linearized) singleunit(missing) I have two variables of interest, patient visits (continuous) and patient severity group (5 mutually exclusive categories). To estimate the average number of patient visits, I simply run: svy: mean visits, over(group) This gives weighted means and appropriate standard errors (and thus the CI) What I next want to estimate in the relative proportion of all patient visits in each of the five groups. For example, the most severe patient group accounts for approximately 60% of all patient visits. I can estimate the overall total of patient visits per group using the command: svy: total visits, over(group) and from that can work out the point estimate of the relative proportion for each of the 5 groups. But I cannot figure out how to get the SE of the relative proportion. This is probably incredibly simple but I have had no luck searching the FAQ, the manual or the list archives.
