My guess is that David's Stata needs updating. In the August 2004
update, -dstdize- was changed so that is saved the standard errors,
lower and upper bounds of the adjusted rates. So Stata has not been
updated since then, the matrices r(lb)' , r(ub)' will not be there
after you run -dstdize-. You can check whether they are there or not by
typing
return list
after using -dstdize-. If not, type
update query
when your computer is linked to the internet and follow all the
instructions. Then type
whelp whatsnew
to see what is new. This is something you should do every month or so,
so you can take advantage of the improvements we are making.
